John Travolta 'working hard to lose weight'

John Travolta is working hard to get back into shape.

The actor says he’s been working out and playing tennis in order to lose some weight.

“I’ve been working hard! Six games of tennis a day plus an hour of weight-lifting. Every day, well, no, six days a week,” John said

John says his wife Kelly Preston, who gave birth to their son Benjamin in November of 2010, has been his inspiration.

“I’m very proud of her, I haven’t seen anyone pull it together that quickly after because she gained a lot with Ben and she just lost it like that,” he said.

“She worked hard at it and hooked up with Kirstie Alley and her Organic Liaison, so she looks great.”
