Sandra Bullock is "absolutely besotted" with Bryan Randall.
The 51-year-old actress - who split from husband Jesse James in 2010 amid allegations he had been unfaithful - has been "quietly dating" the photographer and former model for several months and he has already won over her friends.
A source said: "Sandra first introduced Bryan to her friends at her 4 July party in Austin, Texas, and he was a huge hit.
"They've been trying to take things slowly, and at first Sandra was reluctant to refer to him as her boyfriend, but it's become clear that they're absolutely besotted with each other."
Last year, Sandra - who has a five-year-old son, Louis - was left shaken when an alleged stalker broke into her home, but she feels much more "safe" now she has Bryan to spend time with.
The source added to Grazia magazine: "She feels safe with him and there's a lot of obvious chemistry. Bryan couldn't be more different from Sandra's ex."
The 'Blind Side' actress has previously spoken of how devastated she was when her marriage ended.
She said: "I've been on the floor and I've been heartbroken. I didn't know how I was going to stand up. But I just gave it time. You don't think it will pass when you're in the middle of it, but it does."
