David Hasselhoff's girlfriend turns Baywatch babe after rescuing swimmer

David Hasselhoff's girlfriend has been hailed a hero after saving the life of a panic-stricken swimmer in Mexico.

The actor, who played a lifeguard on popular TV series Baywatch, was snorkelling with Welsh girlfriend Hayley Roberts in the Riviera Maya when she heard the desperate calls from a man who was suffering from cramps.

The 32-year-old blonde, who has been dating Hasselhoff since last year (11), swam to his rescue and pulled him to shore, leaving her Hollywood star boyfriend impressed.

Roberts tells the BBC, "I was busy chasing a turtle when I heard from far away, 'Help! Help!' I looked up and saw a man in distress. I immediately started to swim towards him out of instinct and shouted to David, who wasn't too far away, 'David, the man needs help!'

"Luckily, as I arrived to him another man was already there. The other man and I pulled him in together to where he could stand.

"I said to David, 'I made a rescue.' He said, 'Good job - you could have been on Baywatch.'"
