Katy Perry and Russell Brand held hands in LA yesterday as they arrived at Oprah Winfrey's show. Russell presented the award for best foreign language film with Helen Mirren at the Oscars the night before, and took his mum as his date. Katy jetted in from Austria after the big awards ceremony, but in time to give a surprise performance on Oprah's Ultimate After-Oscar Party. The show also starred Colin Firth. Russell tweeted about his sexy missus, and Katy enjoyed the beautiful day before hopping on a plane to continue touring Europe.
