The former Baywatch actress' hair was slightly hidden under a baseball cap but her drastic transformation was clear for all to see.
Pamela joins the likes of Beyoncé, Charlize Theron, Michelle Williams and Carey Mulligan by chopping her locks.
The 46-year-old debuted her new hair during an outing in LA with ex-husband Rick Salomon who she recently revealed is her boyfriend.
During an interview with Ellen DeGeneres, she said, "I'd say we're best friends with benefits. I don't want to meet anyone else."
"Because you keep going back to the same guys," quipped Ellen. "You're married then you go back!"
The pair wed in Las Vegas in 2007 and were married for ten weeks before filing for divorce citing irreconcilable differences.
