Los Angeles, Dec 7 (IANS): At 40, German supermodel Heidi Klum has given up lingerie modelling because she would no longer feel "comfortable" doing the catwalk wearing only a brassiere and briefs at this age.

"I wouldn't model with my underwear down the runway anymore. I think I would find it a little uncomfortable, maybe,” contactmusic.com quoted Klum as saying.

"I still do photoshoots for (magazine) covers and different things or advertising stuff,” she added.

The mother of four, who split from her husband, singer Seal, in 2012 and is now in a relationship with her former bodyguard Martin Kristen, also said she is happy to get older and embrace the lines of age rather than have surgery.

"I wouldn't say that I love (my crow's feet), but that's just the way it happens, right? We get wrinkles from smiling. I've never had any (cosmetic procedures). I've been too scared, to be honest with you. I'm scared that all of a sudden you're changing too much, your face starts changing, I don't know,” she said.

"I would have a hard time looking in the mirror and seeing something that I'm not used to seeing. I'd be afraid,” added Klum.
