Ok, so there were rumours that Rita Ora was dating Scottish DJ Calvin Harris, and the pair were spotted at the movies last week, but didn't anyone really think this was a serious thing? Well, apparently it is, with the couple stepping out in London last night to celebrate Calvin's win at the Ivor Novello Awards, where he bagged the rather illustrious gong for Songwriter of the Year.

Rita, 22, certainly made an effort for the pair's second date, wearing a stunning floor length red strapless Vivienne Westwood gown with leather jacket and strappy heels. The couple headed to the swanky celebrity haunt Nobu where they enjoyed a fancy meal before heading to a party at Camden's Proud until the early hours of the morning. Yesterday, Rita proudly uploaded a snap of Calvin, 29, clutching his Ivor Novello on her Instagram page. "Ivor novello's eh? Songwriter of the year. No big deal just pretty f****** awesome!! @calvinharris :))))". 

Calvin posted the same snap on his Instagram snap, writing, "Just won Songwriter of the year at the Ivor Novello awards. Proudest moment of my life. Speechless." Rita - who is currently starring in Fast & Furious 6 - is busy working on her own career, rehearsing for a series of festival appearances over the summer.

Rita and Calvin went public with their relationship at the launch party of Daft Punk's new album on the 69th floor of The Shard in London last week. Both musicians joined the likes of Jude Law, Tinie Tempah and Laura Whitmore at the exclusive playback. The couple had begun their first date at the Electric Cinema in London's Notting Hill. They probably saw Iron Man 3, or Star Trek Into Darkness, or The Great Gatsby.
