PIC: Rihanna, Chris Brown Kiss on Lips, Hug at MTV VMAs

Amicable exes or something more?

Rihanna and volatile ex Chris Brown were both winners at Thursday's MTV Video Music Awards at the Staples Center in Los Angeles, and the former couple were happy to celebrate their successes together in front of the world -- with a kiss.

After Rihanna, 24, won the Video of the Year Moonman for "We Found Love," Brown, 23, made sure to stop her as she returned to her seat.

Clad in a gray suit, the "Don't Wake Me Up" singer kissed Rihanna on the lips before giving her a hug, keeping his arm around her waist. (Many audience members were also snapped looking on the former couple in surprise.)

As it happens, Rihanna used the VMAs to debut her newly cropped pixie cut -- reminiscent of the girly 'do she wore during her relationship with Brown, which officially ended in February 2009 following his brutal assault of her.

"He was the love of my life," Rihanna told Oprah Winfrey last month, controversially defending her friendly relationship with Brown.

She added to Winfrey that their run-ins at award shows are still "awkward ... My stomach drops and I have to maintain this poker face and not let it get to the outer part of me. I have to maintain that and suppress it."

She added: "I have forgiven him. It took me a long time. I was angry for a long time."

Earlier this year, multiple sources told Us Weekly that the couple had been secretly hooking up, despite Brown's relationship with model Karrueche Tran. A judge lifted Rihanna's restraining order against Brown in February 2011.
