She’s best known for her outrageous costumes – but Lady Gaga was practically al natural as she soaked up some sun with a mystery man on the rooftop of the luxurious hotel, Fontainebleau Miami Beach on Thursday.

Lady Gaga was wearing a yellow wig, but not much else! In fact, she appeared to be topless as she ‘modestly’ clutched a towel to her chest.

The sultry singer tweeted earlier that she has two shows on New Year’s Eve in Miami and has thirteen outfits! She said she doesn’t care if it’s Miami –she’s still wearing leather.
