Can't young Hollywood just get along?

Courtney Love's daughter Frances Bean Cobain went off on "Keeping Up With the Kardashians" star Kendall Jenner on Twitter this week…but what for?

There are two things the majority of us will never get to do: Become president of the United States and go to the prom in Hawaii. Barack Obama has gotten to do both.

Though the world has seen plenty of pics of the 51-year-old in his presidential role, we're only now getting a peek at his prom night thanks to a former high school classmate of Obama's, who turned the pic over to Time magazine recently.

The photo shows (L-R) Obama's pal Greg Orme, a fellow varsity basketball player; Kelli Allman (nee McCormack), Orme's date and the woman who shared the photo; a cream blazer-wearing Obama; and his date, Megan Hughes. The foursome was heading to the prom at the Punahou School, where three of the foursome were students. Obama's date attended the Hawaii School for Girls at La Pietra.

The shot was taken at Allman's mother's house where the group sipped champagne (uh-oh, they were underage!) before heading to the dance and the afterparty.

Jake Davidson is one lucky fella.

The crafty Los Angeles teenager who unsuccessfully attempted to land Kate Upton as a prom date will be able to slip a corsage onto another gorgeous model's wrist. The high schooler's date on Thursday night will be Danish beauty Nina Agdal, a rep for Elite Model Management confirms to omg!.

Get ready for a serious dose of cuteness ― and super smarts, too! A video has recently gone viral online featuring 4-year-old Mia Grace, whose knowledge about Marvel comic books might just blow you away.

The engaging footage shows her dad asking her a series of questions on pretty much every superhero known to mankind. And get this: she actually answers almost all of them correctly!

So if you thought you were the comic buff, think again! This tiny tot knows the popular characters, and she can actually teach you a thing or two about the lesser known names — even of characters that might make an appearance in "The Avengers 2."

Think you can challenge Mia to an action-figure standoff? Check out this vid to see the little smarty pants in action, and be sure to tune in to "omg! Insider" on TV tonight for more of the latest in entertainment news!

Giuliana and Bill Rancic (Getty Images)The combined forces of nature that are Giuliana and Bill Rancic can be a bit overwhelming. Together, they're entrepreneurs, restaurateurs, reporters, TV stars, fashionistas, survivors, and – oh yeah! – parents.

So how do they pack it all in?

We're still not quite sure, but thankfully, when we caught up with them, they provided us with a little bit of insight. And a lot of fun stories about their adorable nine-month-old baby, Duke.

1. Hooray! Duke sleeps all night.
"We're happy to report that he's just started sleeping through the night, so that was good news," Bill shared. "It's changing everything, now that he's sleeping 11-12 hours at a clip."

"We're definitely getting more sleep now that he's sleeping,"

Well, that's certainly one way to party crash!

A Psy impostor has been hobnobbing around the French Riviera at the Cannes Film Festival this week, tricking partygoers and organizers into thinking he's the real Korean popstar and gaining access to many of the A-List parties.

An onlooker at the famed Torch Beach Club on Wednesday told the New York Post, "He had three security standing with him at all times, surrounding the table in suits and earpieces ... Scamming free drinks and bottle service, including bottles of Cristal Rose."

Brad Pitt (Getty Images)Brad Pitt's memory is shot … at least, when it comes to remembering faces.

The 49-year-old actor says he has developed facial blindness, where after meeting and engaging with someone, that person's face disappears from his memory as soon as they walk away. If they ever come in contact again, to him, it's like meeting an entirely new person.
