But where's her makeout buddy Vito Schnabel?

On Wednesday evening Heidi Klum jetted out of Los Angeles International Airport, and the German supermodel wore a pair of ripped jeans and a sheer black top that showed off her bra. She may be a 40-year-old mother of four, but she's still got it!

Over the weekend Heidi hit the Vanity Fair Oscar party with her new beau, and the day before that the duo attended the Weinstein Co. pre-Oscars party at the Montage hotel in Beverly Hills. "They were seated at a table with Serena Williams and couldn’t stop kissing," a spy tells the New York Daily News. And before that we caught the May/December couple making out at Bootsy Bellows in West Hollywood ... It certainly seems like things are getting serious with them, so when are they going to make an official public appearance together?

She's easily the funniest K sister!

Khloe Kardashian guest hosted Chelsea Lately on Wednesday night, and the reality star didn't hold back with her raunchy jokes, specifically when she addressed rumors O.J. Simpson was her real father!

"I really hope that's not the case because I did f**k him once," she joked before adding, "I did f**k him one time - it's OK!"

The Keeping Up with the Kardashians star also took the opportunity to slam her sister Kim and momager Kris Jenner!

"My mom basically tags around with Kim, follows her around, dresses like Kim. It's like the Kim and Kris syndrome - they've started dressing alike," she told the audience.

We think Khlo should get her own show after seeing how well she did on this one!

Um, #bandwagon much?

On Wednesday Ireland Baldwin posted some sassy selfies on Instagram, and the 18-year-old aspiring model showed off her new purple haircolor. We've never liked this shade on Kelly Osbourne, it looks ridiculous on Nicole Richie (she debuted her new hue over the weekend), so why would we feel any different about Ireland's dye job?

Alec Baldwin and Kim Bassinger's daughter wrote alongside the photo, "Bust my lip and died [sic] my hair. Thank you @anderssonjj for the PURP babe."

We're dying over the fact that she doesn't know how to spell "dye" ... and our opinion? Go back to blonde!

We'd recognize this grunge goddess anywhere!

On Wednesday evening Kristen Stewart left after a long day on the set of Still Alice in New York City, and the 23-year-old actress hid in the backseat of her chauffeured vehicle. K. Stew was clutching a copy of the novel of the same name by Lisa Genova ... we're hoping this is the second time she's reading the book!

The big screen adaptation of Genova's novel is about a psychologist who discovers that she’s suffering from early onset Alzheimer’s disease, and it stars Kate Bosworth, Alec Baldwin and Julianne Moore. The film is set to be released in 2015.

Celebs are just like the rest of us!

Except Matthew McConaughey's dentist is in a ritzy part of Beverly Hills and we're going to go ahead and guess that 80% of the stars in Hollywood have veneers. Anyway...

Matty went to get some dental work done on Wednesday, and he spent a whopping three hours at his appointment. While that doesn't sound like fun, we're guessing the 44-year-old actor is still on cloud nine after winning the Oscar for Best Actor on Sunday. Though there were reports that Matty told The Sun he wouldn't spend much time at the after parties because he wanted to "go home and make another baby" with wife Camila Alves, his rep told E! News the actor never said those words. Still ... we can't help but wonder if that story has some element of truth to it...

On Wednesday afternoon Madonna went to Pilates in Beverly Hills, and she may not be as newsworthy as Justin Bieber or Miley Cyrus, but she apparently felt it was necessary to be accompanied by bodyguards and a pair of police escorts. Really?! Two sheriffs' cars for Madge? I guess she is the queen of pop...

And speaking of Miley, the ladies must have really hit it off when they worked on MTV Unplugged earlier this year, because the two partied together until 6am on Oscar Sunday! Madonna threw a star-studded bash with guests including Ashton Kutcher, Mila Kunis, Jennifer Lawrence and Ellen DeGeneres. Um, that sounds way more fun than the Vanity Fair after party!

P.S. Her face may not look 55, but her hands certainly do:

Even though she's covering up her fab figure, we're sure Justin Bieber still thinks she's a babe!

Selena Gomez wore flats and a loose outfit to the studio in Burbank on Wednesday, and despite Bieber's best efforts to get back into her good graces, apparently she wants nothing to do with him.

On Monday the bad boy pop star posted an Instagram photo of Gomez at the Vanity Fair Oscar after party and wrote, "Most elegant princess in the world," but after seeing this, Gomez reportedly "scoffed" and "laughed out loud when she saw it, saying it was stupid and childish." A source tells TMZ, "[She] isn't falling for Justin's old tricks anymore. She's exercising her rehab knowledge and slamming the door shut on any future relationship."

But do you REALLY think it's over?
