I'm still alive! Jon Bon Jovi family spent Christmas day holidaying in St Barts and taking part in plenty of water sports

She was the New Jersey rocker�s high school sweetheart, and nothing has changed for Jon Bon Jovi and his wife Dorothea.

The couple looked as happy as ever as they continue to enjoy a vacation on the island of St.Barts with their children.

Yesterday, mother-of-four Dorothea showed off her trim beach body in a black one-piece swimsuit.

The black scoop plunging swimsuit with drawstring front and halter neck, highlighted the 49-year-old's flat stomach.

The brunette then revealed a low back detail as she sat in the sand with her two sons Jacob Hurley, nine, and Romeo Jon, seven.

When the Bon Jovi frontman wasn�t getting stuck into a spot of paddle boarding, he couldn�t keep his eyes off his gorgeous spouse.

Jon was spotted last week on the island doing push ups against a bench after hiking up a steep hill.

The images are a stark contrast to the condition he was thought to be in recently, after false rumours spread across the internet that he had died.

Last Tuesday morning, a report on a random WordPress blog, claimed he went into cardiac arrest at the Empress Hotel in his home state of New Jersey and died later in the evening.

Shortly after the rumours surfaced, he tweeted a humorous photograph in response.

With a huge grin on his face, he held up a sign reading: 'Heaven looks a lot like New Jersey - jbj.'
