Liza Minnelli performing at the 5th Annual Broadway Under The Stars Concert held in Central Park New York City, USA- 26.06.06

Minnelli was performing in Coney Island when she stopped at Nathan's Famous for one of their legendary hot dogs.

According to New York Post's Page Six, the star puffed on a cigarette and chatted with the crowd while munching on a hot dog and fries.

Before she left, she handed over her leftovers to a gay male admirer who was thrilled with his souvenir.

Minnelli jokingly asked if she would be seeing the fries for sale on Internet auction site eBay.

The fan gasped and shrieked, "Never".
