The star stepped out Monday night to celebrate Cardi B's birthday. Cardi had a Caribbean dancehall themed party and you know her "Rumors" girl Lizzo stepped into the place. She wore this see through shimmering purple mesh gown over underwear and nipple pasties. Lizzo was one of two hundred guest that partied the night away. The party didn't end until 3:30 in the morning. All the A listers were present and clearly had a great time.
