A skimpy bikini wasn't the only thing heating-up Avril Lavigne's French vacation as RadarOnline.com can reveal the man on the receiving end of her affections was none other than her ex-husband, Deryck Whibley.
The singer has been dating Brody Jenner for over a year, but he was nowhere to be seen as she cozied up to her former flame during a boat trip on the French Riviera.
Sporting a tiny black and purple bikini Lavigne and Whibley could hardly keep the smiles off their faces as they hugged and flirted on board.
At one point the pop punk princess leaned in and affectionately placed her hand on Whibley's stomach.
Just days ago, Lavigne and Jenner were spotted looking loved-up in Toronto, Canada, where she was performing at the MuchMusic Awards.
However, according to his Twitter page, although Jenner did not follow his girl on her European holiday it's definitely not a case of out of sight out of mind.
"Feels nice to be home," he wrote on June 21. "Only one thing missing."
