Kelly Brook has got back together with fiance Billy Zane after she found out he was dating a new woman.

The former model has rekindled her relationship with the American actor after learning he was dating a mystery British actress weeks after she ended their four-year relationship.

A source tells the News Of The World, “She was madly jealous and realised she wanted him back."

The pair were pictured back together in London this week.

However, friends of the former model believe she may have made a mistake in taking Zane back.

"Kelly could have any man in the world. She's panicked but we feel she should have moved on. It's clear he had," one tells the paper.
