Rihanna Almost Loses Her Wig!

Rihanna is wigging out!

Riri had a potentially embarrassing moment last night, when her wig almost came off as she was leaving her favorite dinner spot Giorgio Baldi. Gotta keep that thang on, gurl!

Despite the snafu, things in the sultry star's love life have definitely been looking up. The "Diamonds" singer and Drake's romance has certainly been heating up.

"She knows he has obligations and whatnot but he treats her as if she’s the only thing that matters,” a source told HollywoodLife.com. “They’re too much in love and the honeymoon stage has already come and gone.”

On Sunday, the 26-year-old Barbados-born singer took the stage with Eminem for MTV Movie Awards to perform their hit song "Monster," and the pair definitely rocked the house!
