Joe Jonas, Ashley Greene go public with their romance

London (ANI): Singer Joe Jonas and Twilight star Ashley Greene are going public with their romance. The couple, who have been quietly dating for several months, have always maintained that they are 'just friends'.

But yesterday they were spotted out and about in Beverly Hills walking with their arms wrapped around each other, and later holding hands, reports the Daily Mail. The two first went for some lunch before hitting the shops for a few hours of retail therapy. The 21-year-old singer was later seen carrying their many purchases to his waiting Porsche.

The couple then headed off to celebrate Joe's little brother Frankie's 10th birthday. Ashley, 23, was in town to attend the premiere of Twilight, in which she starred as Alice Cullen, and Joe was there to support his brother Nick in his stage debut, appearing in Les Miserables.
