The 'Gravity' singer - who recently split from 'Friends' actress Jennifer Aniston - reportedly lowered his trousers and danced around in front of the 'Project Runway' host at a nightclub in New York's trendy SoHo district, making her laugh hysterically.
However, according to the New York Daily News newspaper, sources close to Heidi - who is married to singer Seal - have played down reports she was flirting with the 30-year-old singer, insisting the pair are just old friends.
