The blonde bombshell – who's been married three times and has two sons, Brandon, 13, and 11-year-old Dylan – is dating electrician and surfer Jamie Padgett.
Romance sparked a few months ago after they met in a Malibu trailer park where she's been living during renovations to her home.
The pair have been inseparable ever since Jamie, who is the father of two boys, offered her a ride to the beach in one of the golf carts used as transport in the park.
“She is more in love than I have ever seen her before,” a source told a US publication. “He’s a totally moral, nice, normal guy.”
Pam certainly gave the impression of being loved-up during her trip to Montenegro this week. Though she's in the country to discuss investment opportunities, the model and businesswoman also spent plenty of time chilling out and soaking up the sun with her new man.
Their afternoons have been spent cruising the crystal waters off the bay of coastal town Budva on a luxury yacht. Onlookers reported seeing them cuddling, soaking up the sun and enjoying long lunches together.
The relationship comes after marriages to musicians Kid Rock in 2006 and Tommy Lee, whom she wed in 1995 after knowing him for 96 hours.
In November 2007 she also tied the knot with professional poker player Rick Salomon in Las Vegas during a break between her two nightly appearances in a magic show, but by the following February the union was over.
