Is Catelynn Lowell dissing former "Teen Mom" co-star Farrah Abraham's sex tape?

That appeared to be the case when Lowell sent a cryptic tweet about an unnamed person on the very day that Abraham's sex tape, "Farrah Superstar: Backdoor Teen Mom," was released.

"All I have to say Is she sounds like a dying horse!!" wrote Lowell, the mother of Carly, whom she gave up for adoption. "U kno who I'm talking about."

The tweet was punctuated with an emoticon laughing so hard it was in tears.

Talk show host Wendy Williams turned heads on the red carpet Sunday night at the Broadway.com Audience Choice Awards in New York City when she showed off her svelte shape and small waist in a plunging, shimmering evening gown. And Williams, who hosted the event and will soon star in the Broadway production of "Chicago," has good reason to want to flaunt her figure … she's worked for it!

The 5'11" wig wearer recently announced on her online "After Show" segment that she's dropped 20 pounds since last May and is now down to 175 pounds. "[My weight] is under control although it can spin out of control at any given time. You know I love my food," Williams, 48, explains in the video, adding that she decided to drop the weight to get ready for turning the big 5-0 next summer.

LaToya Jackson talks to omg!. (Valerie Macon/Getty Images)Whatever you think of La Toya Jackson and the rest of her family, she wants you to know you're probably wrong.

"I think that when it comes to the Jacksons in general is that people think that they’re weird. They’re strange. They’re crazy. They're odd. And we're not,” she tells omg!. “We’re not any of those things. I want people to know that we’re just like you guys are. We're no different."

And if you also thought that Jackson, now 56, might have been jealous of her more famous siblings, the late Michael (who passed away in 2009 at age 50) and sister Janet, now 46, well, wrong again.

Brooke Mueller (PacificCoastNews.com)Just a day after her 4-year-old twin boys were removed from her care by the Los Angeles County Department of Children and Family Services, Charlie Sheen's ex-wife Brooke Mueller checked into a rehab facility.

"Despite reports to the contrary, Brooke is currently at UCLA Medical Center where she has been since being admitted May 3," Mueller’s publicist, Steve Honig, told omg! in a statement. "Brooke will be there for several more days, and will likely transition directly into a residential treatment facility to get help for prescription drug abuse. Brooke misses her children, and wants to get healthy so she can resume her life and get back to being a mom."

After Bob and Max, her sons with Sheen, were removed from her home last week, they were temporarily placed with the woman Sheen was married to prior to Mueller, 42-year-old actress Denise Richards.

Jennifer Lopez looked like she was wearing nothing but her birthday suit in Fort Lauderdale, Florida, on Sunday on the set of her latest music video, "Live It Up." But it turns out it was just an optical illusion (much to the dismay of her male fans, we bet). The brunette bombshell sported a nude-colored one-piece that was so similar to her skin tone, it definitely left little to the imagination. Ooh-la--la! She accented the ensemble with beachy tousled hair, smoky eye makeup, and orange lipstick. Now we see why beau Casper Smart kept a close watch on her during the shoot with rapper Pitbull.

But that wasn't the only sexy look the 43-year-old superstar rocked. She also donned a printed green caftan over a black bikini, which looked strikingly similar to the infamous Versace gown she wore to the 2000 Grammy Awards.

Check out the video to see more of her sultry style, and tune in to "omg! Insider" on TV for the latest entertainment news!

Jane Levy on April 16, 2013 in London, England (Fred Duval/FilmMagic) Jane Levy, who plays wisecracking teen Tessa Altman on the ABC sitcom "Suburgatory," filed for divorce on April 16 from actor Jaime Freitas.

Didn't know she was married? Yeah, neither did we.

Court documents show that the marriage lasted only seven months. The two married in March 3, 2011 and separated on October 31, 2011 (guessing they had a bad Halloween?). but Levy didn't formally file for divorce until a few weeks ago. They are reportedly still friendly, although in her filing, citing irreconcilable differences, Levy states that she doesn't want to pay spousal support. TMZ was the first to report the divorce news.

Levy, 23, is also well-known for her starring role in the remake of "Evil Dead," which just hit theaters in April 2013. She first turned heads with a five-episode arc on Showtime's "Shameless." There's not much out there about Freitas, other than that he's been in quite a few foreign films, at least, according to his IMDb profile.

There's very little public indication that Levy and Freitas were even a couple -- no big

Keira Knightley may be the most low-key celebrity bride ever.

Over the weekend, the 28-year-old "Pirates of the Caribbean" star married musician James Righton in southern France -- and it appears that she may have recycled her wedding dress.

That's right -- the simple, yet stylish, short, strapless tulle dress Knightley was seen wearing as she joyfully skipped out of her wedding ceremony while clutching the hand of her groom seems to be her something old. The gown appears to be the same one she wore to a pre-BAFTA party in 2008.

Blue Ivy is clearly "Irreplaceable," but could there be a new "Baby Boy" in the Carter/Knowles household in the near future?

Beyoncé brought her 15-month-old daughter out on stage on Saturday during her concert at London's O2 arena. As Bey belted out her 2006 hit song, she briefly grabbed her little girl who was watching from the front row. Blue Ivy was wearing a white dress and large headphones.
