(FameFlynet Pictures) While everyone was obsessing over whether or not Rihanna was really back with Chris Brown, the singer was apparently able to sneak under the radar with a new man. So who's the lucky guy? Well, it's none other than Ashton Kutcher, so we hear.

Earlier this week, Rihanna was seen arriving at Kutcher's pad around midnight. She only reappeared at about 4a.m., according to trusty spies set up to stand guard. And by "trusty spies" we mean the paparazzi.

British tabloid The Sun, which isn't the most reliable of sources, claims the singer and actor have been getting hot and heavy since January. And, a new story from the tabloid today suggests Rihanna wants Mr. Kutcher to spend the summer with her in London while she tours there. So it's serious, right?

So, how plausible is it that these two are really an item? Well, turns out they do travel in some of the same A-list circles. Sort of. Get this: Rihanna was taken under Jay-Z's wing way back when, and Mr. Z is friends with Diddy, who is good pals with Kutcher. That's just a few degrees of separation, folks.

Naturally, neither star has even remotely addressed the juicy new rumors. Their publicists have steered clear, too.
