If you think Heidi Klum, you almost immediately think style, elegance and sophistication. But that’s not to say that she takes herself too seriously: at the Elton John Oscar party, the supermodel took off her underwear for a Jay Leno goody bag.

The star was at the party in the company of her husband Seal, looking every inch the glamour vixen we’ve known her to be for years, in a flashy Julien MacDonald with a cut all the way up to her thigh.

Reporter Ross Matthews had also made his way into the star-studded bash, asking celebrities to give something – a personal trifle – for a good bag he was working on for Jay Leno.

When he approached Heidi, she initially looked in her purse for something to give away. Almost immediately, she realized she had nothing there she could do without – so she chose something a bit more personal.

Like, the very underwear she had on her, as the video below will show and Metro confirms.

“I don’t have a lot in here that I can give you,” Heidi told Matthews, before coming up with what she considered the best idea for a gift.

“Oh, you can have my underwear. Wait, do you want my underwear?” she asked.

The next instant, she was already taking it off and handing it to Matthews, who placed it in the good bag for Leno.

“Jay will like that,” Matthews laughed.

Other celebrities were also very generous and made donations on the same occasion, at Elton John’s fabulous annual party.

Jamie Foxx, for instance, took off his designer shades and handed them to Matthews, who even joked about keeping them because they were too awesome.

Jane Lynch of “Glee” gave Leno a Visa card but, “unfortunately,” it had a $2,000 per day limit. Diminute actress Hayden Panatierre also had something more personal for the talk show host, though not as personal as Heidi’s.

Hayden took a napkin and left the print of her lips in red lipstick on it.
