Ridin' with Gerry. - Getty ImagesWhile Justin Timberlake seems to be linked to a new starlet with each passing day -- Ashley Olsen, Mila Kunis, Olivia Wilde, to name a few -- not much has been heard from Jessica Biel since the couple's split.

Until this weekend. (Hopefully you read that sentence in Ominous Movie Trailer Narrator Voice.)

TMZ has just published a 40-picture (!) slideshow of Biel riding on the back of Gerard Butler's motorcycle down the PCH in Malibu over the weekend. The two were rumored to be friendly on the set of "Playing the Field," the movie they recently shot in Shreveport, Louisiana, but this is the first sign that they may be more than friends.

People has some quotes from observers on set which are pretty hilarious.

Like this one:

"He knows he looks good," the onlooker tells PEOPLE. "If I were her, I'd hook up with him. She looks good, too, and she knew she looked good, swinging her hips around."

Also this one:

"Gerry has a large personality, and everyone, including Jessica, gets caught up in

He looks like Bradley Cooper ... minus the fashion sense. - Jeff Kravitz/FilmMagicWhat the what? After dating for a nanosecond, Nikki Reed and Paul McDonald are engaged. Just like that. The "Twilight" actress flashed a diamond ring on the red carpet at Sunday's MTV Movie Awards, repeating: "He's the one. He's the one."

McDonald is a Bradley Cooper lookalike and singer with blindingly white teeth who appeared on the past season of "American Idol." Reed brought him as her plus one to the ceremony, where "Twilight" dominated as "Best Movie" and "Best Kiss," memorably.

Apparently, the whirlwind romance began just a few months ago when Reed began Skyping McDonald from the set of "Breaking Dawn."

Skype = the new Match.com.

Last week brought news of two high-profile celebrity break-ups, as it was reported by reputable sources that Scarlett Johansson and Sean Penn, as well as Cameron Diaz and Alex Rodriguez, had called it quits.

But observers at the two major awards shows this weekend -- the Spike TV Awards Saturday night and the MTV Movie Awards Sunday night -- noted apparent reunions between both couples.

On Saturday night, Penn and Johansson posed for a photograph together backstage. Now, this certainly doesn't mean they are dating again or anything like that, but -- considering they were extremely private about their relationship when they were dating -- it seems somewhat curious. We will note that they both look a bit uncomfortable (Penn more so than Johansson) in the picture.

Meanwhile, on Sunday night, Diaz and Rodriguez dispelled rumors of their own split more convincingly, as they stayed close at the MTV Movie Awards afterparty and were "very affectionate" and held hands. (They were also seen

The Southern belle unleashes her feisty side. - Jeffrey Mayer/WireImageIt's pretty rare to hear Reese Witherspoon say what she really thinks about anything, so we were pleasantly surprised by her out-of-nowhere rant against sexting starlets at the MTV Movie Awards. While accepting an "MTV Generation Award," the 35-year-old actress directed her speech to all the aspiring Kim Kardashians out there:

"I get it, girls, that it's cool to be a bad girl. But it is possible to make it in Hollywood without doing a reality show. When I came up in the business, if you made a sex tape, you were embarrassed and you hid it under your bed. And if you took naked pictures of yourself on your cellphone, you hide your face, people! Hide your face!"

Lindsay Lohan, of all people, agreed. "I love reese witherspoon sooooo much!!!!" she tweeted, most likely ecstatic that she has thusly managed to avoid the leakage of any sex tapes and/or illicit iPhone photos.

Blake Lively, who was a presenter at Sunday's show, cannot say the same thing. So far, Leo DiCaprio's va-va-voom new

Two tweets so far... - Getty ImagesGwyneth Paltrow has been on Twitter since Wednesday now -- amassing close to 90,000 followers already -- and, we have to say, we're liking what we're seeing, though we wouldn't mind at all if she started tweeting just a little bit more frequently.

Paltrow has only tweeted twice since joining the site. The first was a surprisingly intimate video in which she explained her desire to "join the 21st century" and enter the worlds of Facebook and Twitter.

She then posted this shot of Moses and Apple (who are rarely seen in public) at a "secret" Coldplay show on Thursday. This one was great. It gave us a peek behind the curtain and offered us a picture (which is always a plus).

So far, GP is only following three celebrities: her husband's band, Samantha Ronson (curious) and Brit comedian Simon Pegg (curiouser). One wonders if, now that she appears on her way to catching the Twitter bug, Paltrow will eventually try to convince BFFs Beyonce and Jay-Z to come on board.

Pregnant in heels. - FilmMagicBad Mommy Patrol is on alert: Ivanka Trump plans on returning to the boardroom just two weeks after giving birth to her first child.

"I have meetings on the calendar two weeks after my (July 14) due date, but of course, I'll have to get to know the baby's needs first," Trump told an incredulous In Touch magazine reporter (via Celebitchy).

BMP reaction: "Ivanka is a selfish workaholic whose nanny will end up raising her daughter full-time. If only less wealthy working mothers had the luxury! But wait! There's plenty of working mothers who would gladly take extended leave to care for their baby, and since Ivanka really doesn't need to pay the bills, why would she go back to work right away? HALF-ASSED MOM."

Our reaction: "Plenty of new moms take two weeks off for whatever reason, and Ivanka is only going to some meetings. Who cares?"

Our biggest concern: "What kind of first-time mom assumes their baby will be born on its EXACT DUE DATE, and schedules important business appointments

The couple, way back when. - Getty ImagesWe're dealing with Kelsey and Camille Grammer here, so nothing should really come as a surprise, but this latest move by Kelsey in their ongoing custody battle is truly bizarre.

According to documents obtained by TMZ, Kelsey has petitioned for primary physical custody of his 6-year-old son Jude, who would move to Chicago to live with him and new wife Kayte Walsh. However, per the proposal, 9-year-old daughter Mason would stay in California, under the primary physical custody of Camille.

He suggests they each share joint legal custody of both children, with each parent having both children one weekend per month. (They would also spend Mother's Day with Camille, Father's Day with Kelsey, and one month per summer with the other parent.)

Camille, unsurprisingly, is not so jazzed about this plan and has already filed a motion that both children live with her.

The first hearing in this custody mess is scheduled for June 9 and, to be honest, we can't wait.

Today John Edwards got indicted, Jack Kevorkian passed away and Blake and Leo are chilling on another love boat in Venice, Italy. Amid all this NEWS, we can't get over the gripping distraction that is this clip of National Spelling Bee champ Sukanya Roy winning by a "cymotrichous":

It's fun to watch Roy, 14, visualize the word in her mind, spell it with her fingers and then realize she won the $40,000 prize. Oh, and the judge's Bon Jovi reference is priceless in pretentious context -- especially since cymotrichous (which we'd never heard or read in our lives before this) means something that relates to wavy hair. Turns out, Roy actually knew the word anyway -- from studying the good old dictionary.
