Heidi Klum lax sheer blonde denim airport model project runway

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?
