Pic: Are Caroline Wozniacki and NFL star JJ Watt an item?

It's pretty hard to upgrade from golf's world number 1, but it looks like Caroline Wozniacki could be doing a line with NFL defensive player of the year JJ Watt

Nearly a year after Rory McIlroy called off their wedding plans, and on the eve of the Irishman's bid to win a first green jacket at the Masters, the Danish tennis star, herself a former world number one, attended last night's NCAA college basketball final alongside Watt, who was supporting his alma mater Wisconsin against Duke. And the pair were happy to be pictured together during the thrilling game in Indianapolis, as Duke came from behind to disappoint Watt and the Badgers with a 68-63 triumph.
