Is Rihanna Into Two and a Half Men?

Now, here's an odd couple. "Birthday Cake" singer Rihanna may be dating - or possibly just shagging -- up. Well, at least when compared to ex-boyfriend/batterer Chris Brown. The 24-year-old Barbados beauty was spotted leaving the Los Angeles home of Two and a Half Men star Ashton Kutcher after a late night. According to Radaronline.com, the "Take Care" singer spent about four hours behind closed doors with the Hollywood hunk this week. It's not that surprising because both parties are living the single life. While Rihanna has been linked to Brown recently, Kutcher has been hanging solo for the most part following his split from wife Demi Moore. Ironically, the timing of Rihanna's midnight rendezvous is somewhat suspect, especially since there are signs there might be trouble in paradise between her and Brown. Brown Tweeted, "At Eternity's Gate" and changed his profile picture to the Vincent van Gogh painting Sorrowing Old Man ('At Eternity's Gate'), which shows a despondent man with his head in hands. Hollywoodlife.com suspects that perhaps Rihanna gave Brown the boot once again and ran right into the arms of Kutcher.
