Amanda Seyfried left London's BBC Radio 1 studios today and was met by a crowd of fans. The Red Riding Hood actress is overseas promoting her film with her handsome cast while her boyfriend, Ryan Phillippe, is also jetting around Europe with his The Lincoln Lawyer costar Matthew McConaughey. Amanda's international press tour has been fairly low-key, but back in LA two of her Now costars, Justin Timberlake and Olivia Wilde, have been causing a stir with their flirty dancing. Olivia took to Twitter to squash the gossip surrounding their most recent date night, though it's just the latest rumor attached to Justin. He recently split from longtime girlfriend Jessica Biel and was also briefly connected to his Friends With Benefits love interest Mila Kunis before she made it clear that their romantic chemistry is only make believe.
