The âWe can't stop' hit maker, who had recently stopped following the Aussie actor on Twitter, has ended months of speculation that their relationship was on the rocks, through her rep, the Mirror reported.
However, no apparent reason has been given for the break-up by her rep. The couple, who got engaged in May 2012, first met on the set of their movie âThe Last Song'.
