Rihanna might be denying that Chris Brown is her new boyfriend ... but she can't deny that she's got a new tattoo!
Rihanna and Chris Brown attended an evening party together the other night in New york, and RiRi showed off a brand new tattoo that decorates her back!
A bundle of stars plunging from her neck down her back. This makes a total of five tats for the singer.
If you're curious to know what the other four tats are; a music note on her ankle, a Pisces behind her right ear, a star inside her left ear and a Sanskrit prayer going down her hip.
Rihanna's been spotted in and out of tattoo parlors for a while now ... and we were trying to spot the new tat, but that was a tad bit difficult because it was hidden under her clothes.

What do you think of Rihanna's new starry tattoo? Hot or Not?
