Heidi Klum likes to have her breasts on show on 'America's Got Talent'

Referring to her assets by her nickname for them, Hans and Franz, she told People StyleWatch: ""When I do AGT, most of the time I sit behind a desk, so it's really from the waist up.

"So I look for something that is of interest around here. And usually, I like to have Hans and Franz on a good display."

Heidi's other important consideration is to make the outfit more interesting than just plain colour.

She continued: "It's usually sequins or something with a great texture. I love big earrings or doing different things with my hair.

"Sofía [Vergara, her co-judge] and I have a good beauty and fashion thing going.

"Last week she was in yellow, and I was in red and people made ketchup and mustard memes."

Heidi - who is married to Tom Kaulitz and has four children with ex-husband Seal - joked she is a "hoarder" when it comes to holding on to her old outfits, but insisted she

does wear her clothes more than once so they're always worth holding on to.

She said: "I have a really hard time throwing things away, because I know I'm going to wear this again at some point, and I do."

The blonde beauty noted her personal style is always changing.

She said: "I want to dress however my mood is that day."
