Heidi Klum has given up lingerie modelling.

The 40-year-old supermodel says she would no longer feel ''comfortable'' on a catwalk wearing only a bra and briefs.

She told TV show Access Hollywood live: ''I wouldn't model with my underwear down the runway anymore. I think I would find it a little uncomfortable, maybe.

''I still do photoshoots for [magazine] covers and different things or advertising stuff.''

The mother of four - who split from her husband, singer Seal, in 2012 and his 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.

She said: ''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

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