Fire up those Rihanna and Drake dating rumors again!

The exes were spotted leaving an MTV Video Music Awards after-party within mere minutes of each other.

Suspicious timing, yes, but it could also be a complete coincidence. Lots of celebs attended the bash at the PhD club in NYC's Dream Downtown hotel directly following the VMAs on Sunday (Aug. 25).

BUT there's also word that the pair were seen together a couple of days earlier. Spies caught them dining with friends in another New York hotspot late Friday night (Aug. 23). The group of 10 reportedly enjoyed lobster and cocktails.

"They sat in a back room, the lights were dimmed, and there was sort of a barricade of tables blocking their group off," a source says. "Drake and Rihanna sat right across the table from one another. They were avoiding photos, and the security kindly asked some fans to leave, because they were trying to get too close."

But one restaurant goer says that it didn't look as if anything especially torrid was happening between the stars. "They looked like they were just having fun," the witness reports. "It didn't seem romantic or overly flirty."

RiRi and Drizzy had dated in 2010 and 2011; rumors of a rekindled romance reignited back in July, following Rihanna's split with Chris Brown.

It's funny, we said Rihanna looked "strangely disinterested" during Drake's VMAs performance ... maybe she was just impatient to hit the town with him?
