Heidi Klum Hits out at Critics Who Say She Is 'Too Old to Model' The 44-year-old model appeared on The Ellen DeGeneres Show with some tough words for her critics. Sometimes people say, ‘You know you’re 44, you’re turning 45, why are you not giving the baton to someone else?’ But I always think there’s a lot of women my age 50, 60, 70. What, do we have an expiration date? Can we not also still feel sexy? I feel sexy. Klum also revealed that she's ready to start dating again after ending her three-year relationship with Vito Schnabel in September. I'm very single and very ready to mingle.
