British pop star Max George has reportedly ended his romance with model Nina Agdal after less than six months of dating. The Wanted star befriended Adam Levine's ex-girlfriend after appearing together in an advertising campaign for fashion brand Buffalo over a year ago, and they became a couple last August (13). However, the pair has since parted ways, according to Britain's Sun on Sunday newspaper. A source says, "They just wanted different things out of the relationship and had grown slightly apart." The news emerges a week after Agdal was photographed leaving a New York club with Leonardo DiCaprio after celebrating the Super Bowl last Sunday (02Feb14). The split will mark a fresh start for George as he prepares to embark on an indefinite hiatus from The Wanted following the completion of their upcoming tour.
