Rihanna Goes Braless In See-Through Dress; Chris Brown Parties With Karrueche Tran [PHOTOS]

While out on Thursday night at Hollywood club Eden, Rihanna partied in a black mini-dress — braless.

It is clear Rihanna knew her exposed breasts would be seen, especially with the paparazzi’s flashing lights, as she tried covering her chest with her hands when she entered the club, to no avail.

Rihanna is often seen without clothes—thanks to Instagram photos she uploads of herself.

She is also nude and unapologetic on the cover of her latest album.

While Rihanna attended Eden by herself, Chris Brown, her on-and-off again boyfriend, was spending time with his ex-girlfriends, Draya Michele and Karrueche Tran, at Michele’s birthday party.

Meanwhile, last week, Brown and Rihanna were spotted in West Hollywood leaving and entering the same recording studio.

Though they left separately, a spokesperson for Brown confirmed to E! News that the two are working on their second single together.

There is no hint as to what the song will be about, but based on previous songs they have worked on collaboratively; it will likely be about their unique relationship.

Brown already collaborated with Rihanna for the song, "Nobodies Business," which is featured on her seventh studio album, "Unapologetic."

Previously, they worked on the hit single, "Umbrella," together, then remixed each other’s singles, Rihanna’s "Birthday Cake," and Brown’s "Turn Up The Music."
