{blackbabes} Rihanna Reunites With Matt Kemp in London! Are They Back Together?

Has Rihanna gone back to the well?

It looked that way in London last night, when she was caught leaving a strip club with her former boyfriend Matt Kemp!

She called it quits with pro-baseballer late last year, but clearly, they're still friends.

And maybe more...?

The exes stepped out together Thursday night and left the club around 1:30 a.m. Nothing's more romantic than watching other girls take it off with your guy, right?

And while Rihanna told me months ago that she loved being single, she sounds like she's ready for a relationship again.

When one fan asked if she's single, she tweeted: "unfortunately! And probably will be for a whiiiiilllleee!!!!!"

Perhaps Ri-Ri just needed some male attention after her latest video costar, fighter/model Dudley O'Shaughnessy, said he was too busy to date her?

Forget going bad. This former good girl has gone boyless.
