The future Mrs. Justin Timberlake stunned on the red carpet at Sunday's MTV Movie Awards in L.A., opting for a long sleeve white knit dress by Chanel.

Also turning heads at Sunday's big show? New mom Charlize Theron, who wowed in a red Lanvin frock and strappy sandals. The elegant sheath was a must for Theron, because of its ease of wear. "You have to just not try to be trendy and do what's comfortable," the Prometheus actress told MTV's Kat Graham of her look. "At the end of the day, I have to put it on and look like me."
