{blackbabes} Rihanna Is Not Dating Colin Farrell

Rihanna is newly single after splitting from baseball pro Matt Kemp, but she isn't moving on to Colin Farrell.

Reports circulated that the singer, 23, and actor, 34, were dating after they were both spotted at an L.A. restaurant on Wednesday night – and a source says they weren't there together.

"They are not dating," the source tells PEOPLE. "It was absolute coincidence they were at Giorgio Baldi at the same time. Colin was there at a business dinner and Rihanna was across the room."

And this isn't the first time rumors have swirled about the two celebrities getting cozy.

In February, reports circulated that they were "sexting" back and forth after meeting for the first time on the U.K.'s Graham Norton Show.

Those claims, the source says, are also false, and Farrell's rep has no comment.

Says the source: "There's no truth whatsoever to the reports and rumors that they're dating."
