When you’re a superstar like Rihanna, one outfit per night just isn’t enough!

The songbird celebrated the release of her new album R Rated in NYC Tuesday night with two smoking hot ensembles.

When Ri arrived at Juliet’s Supper Club at 1 AM, she was clad in arty, spiky golden minidress. But 20 minutes into the fete, Rihanna got so over her outfit and changed into something a little more ‘comfortable.’ And by ‘comfortable’ we mean a boob-baring bright red hooded tube dress and thigh highs — a look we like to call Rihanna-Meets-Lady Gaga. Hot!

“Rihanna definitely wanted to be comfortable,” says an eyewitness, of the clothing exchange. “She walked in with one fierce outfit, changed midway and walked out with a different one! There’s one thing you can’t deny about the girl: she always looks high fashion and fabulous.”

The singer continued to celebrate her album release by taking some much-needed chilled out time, and relaxed in a VIP section of the venue sipping on a glass of champagne.

Congrats Rihanna – on both your album AND your wardrobe!
