Miley Cyrus will reportedly hit the stage with Robin Thicke to perform his summer anthem Blurred Lines at the MTV Video Music Awards on Sunday (25Aug13). Cyrus joined Thicke and collaborator Pharrell Williams onstage to dance at a MySpace relaunch party in Los Angeles in June (13), but on Sunday she'll actually perform with the duo. Getting ready for her big night at the VMAs, during which she'll also perform her hit We Can't Stop, Miley tweeted, "Today's already the f-cking best day ever! Just wait till VMAs tonight." On the red carpet, Thicke said, "We're gonna bring the love and the sexy tonight." Cyrus' We Can't Stop is nominated for Best Female Video, Video of the Year and Best Editing, while Thicke's Blurred Lines is up for Video of the Year, Best Male Video and Best Collaboration. Both promos were directed by Diane Martel.
