Rihanna and Drake dating again?

A source told UsMagazine.com, "Rihanna was all over Drake this weekend. They were holding hands and dancing all close on the dance floor."

The pair dated in 2009 but even after breaking up, they have stayed close - Drake guested on RiRi's "What's My Name" in 2010 and, more recently, the beauty from Barbados loaned her sultry vocals to the title track from Drake's most recent record, Take Care.

Watch the music videos for their collaborations respectively here and here - do you think there's romance in the air?

Drake was recently linked to model Tyra Banks.
