Could Rihanna really be dating Ashton Kutcher? The singer was reportedly spotted stopping by the "Two and a Half Menstar's bachelor pad earlier this week.  According to RadarOnline photographers witnessed RiRi's arrival at his place at midnight, and didn't see her again until the wee hours of the morning when she left after 4am.

Rihanna was thought to be seeing her on-again off-again beau Chris Brown, but those rumors were squashed when Breezy made some puzzling changes to his Twitter account Thursday.  Brown changed his Twitter profile picture to a Vincent Van Gogh painting of a man crying titled "Old Man in Sorrow on the Threshold of Eternity."  This was followed by a tweet that read "At Eternity's Gate."

Ok, so it seems things are through between Rihanna and Chris, but is Ashton her new man?  The two Hollywood A-listers are not as different as many would think.  Kutcher also just got out of a high-profile relationship, a six year marriage to fellow actress Demi Moore.  Additionally, Rihanna and Ashton have overlapping social circles—Rihanna's mentor Jay-Z is friends with Diddy, a close companion of Kutcher's.
