Bradley Cooper's ex Jennifer Esposito calls off engagement to Aussie tennis hunk Mark Philippoussis

Jennifer Esposito has called off her engagement to Aussie tennis star Mark Philippoussis after less than a year of dating. The pair planned to tie the knot in May or June and were shopping the story around to various women’s mags. But now the two have split, citing "irreconcilable differences." A source close to both explains:

They just couldn't get along. Mark wanted to live in San Diego and Jennifer is a native New Yorker; the issue of where to live was emblematic of deeper problems in their relationship.

Jennifer was married to The Hangover star Bradley Cooper for four months back in 2007, meanwhile Mark has dated Delta Goodrem, Paris Hilton and Tara Reid.

The two seem to have rebounded quickly. Last month Mark was spotted with several different women in LA and Jennifer was recently seen cuddling and holding hands with a hot new man in New York’s Meatpacking District.
