jeans Heidi Klum hat sunglasses lax purse divorce seal

That was a quick trip to New York!

Last night Heidi Klum attended the annual amfAR Gala for Mercedes-Benz Fashion Week in NYC, but the supermodel is already back in lovely Los Angeles, presumably to be with her 4 children. We snapped her at LAX this afternoon, and it looks like she's ready to take it easy and move on from her recent and shocking split from husband Seal.

Heidi was all smiles at the event last night, but a source tells Us Magazine that she's still keeping a low profile. "Heidi is trying to focus on work and her kids in this time of heartbreak," the insider revealed. "She most definitely wouldn't be out [last night] if it wasn't to support a charity she believes in."
