Ryan Gosling valentine's day mystery girl

What is going on?! On Friday night, Hollywood heartthrob Ryan Gosling rolled solo to a bar in the valley and on Sunday night was with sister Mandi Gosling.

Despite rumors of a break up, the other day we caught the 33-year-old driving Eva Mendes' car, so we thought the on-again/off-again were still together. Plus, her rep said they hadn't split, so then why on earth would Ryan be at a bar by himself on the most romantic of holidays and then with his sister on Valentine's Day weekend?! Maybe she is helping him mend his broken heart!

None of this makes sense!

As if the hunky Canadian didn't have enough girl problems -- Ryan's ex Sandra Bullock is supposedly scared of bumping into him at the Oscars next month. Sandra is reportedly nervous about coming face-to-face with Ryan this awards season because he really broke her heart years ago, a source close to the actress told Radar.

Despite the 16 year age difference, Bullock, 49, and Gosling, 33, dated from 2002-2003 after meeting on the set of their thriller, Murder by Numbers. The source added, Sandra is totally mortified about being around Ryan, even though shes the one who helped launch his career more than ten years ago. Its crazy, but the fact that he and Eva are taking a break from their romance has Sandy nervous. With everything shes been through with men, the last thing she needs is to have all that brought up again.
