Controversy rocks MTV Movie Awards

Mila Kunis and Justin Timberlake have maintained that they are not dating, but what happened at the 2011 MTV Movie Awards recently, tells a different story altogether.

The two groped each other and offended some sensibilities while presenting the Best Male Performance trophy to Robert Pattinson. While on stage Mila said, "We are like brother and sister." "Totally platonic relationship, which is why I can do this," Justin added.

Singers Britney Spears and Rihanna shared a quick kiss at the Billboard Awards, reminding onlookers of the lip-lock between Madonna and Britney eight years ago. Spears and Rihanna, clad in matching bondage-style costumes complete with buckles, straps and fish-nets, opened the awards night with a saucy performance. They also sported masks, took part in a pillow fight, and when feathers flew into the air, the singers kissed each other.
