Sandra Bullock is "absolutely besotted" with Bryan Randall. The 51-year-old actress 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 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."
