Simon Baker and his wife of 29 years Rebecca Rigg only officially announced their shock split just over a month ago.
But it seems The Mentalist star hasn't wasted any time diving straight into a new romance with a lucky mystery lady.
The Aussie actor, 51, was spotted splashing – and snuggling – with his new squeeze at a beach in Byron Bay on February 28.
And the dad-of-three looked suitably smitten with his much younger looking girlfriend, as the pair both showed off their impressive beach bods.
Indeed, Simon's mystery woman appears closer in age to his eldest child, daughter Stella, 27, than she does to his ex Rebecca, 53, with whom he also shares sons Claude, 22, and Harry, 19.
But despite his new romance, the actor insists he and his former wife "remain close friends."
There's now buzz that Simon, who owns a farm outside the famous celebrity enclave, could be moving back to Oz for good as he and Rebecca have put their former six-bedroom home in Santa Monica on the market for $8.1 million.
Whatever comes next, it looks as though Simon is moving on to another new chapter - one filled with sea and surf.
