Sandra Bullock is over the moon with her new family life. The Oscar Award-winning actress' photographer boyfriend of one year, Bryan Randall, has moved into her home, and the couple lives together as a family with her two young adopted children, E! News reported. The "Miss Congeniality" star has been spending quality time with her man and her kids, which is why she seems to be at her "happiest" right now.

"Bryan has officially moved in with Sandra," a source told E! News. "He still has his home as well, but lives with Sandra full time. They have been spending most of their time together."

The news comes just two months after Bullock, 51, introduced her new adopted daughter to the world with a special People Magazine cover story. In her interview, she revealed that she adopted 3-year-old Laila (pronounced Lila), who was previously in Louisiana under foster care. Bullock is also mom to her adopted 5-year-old son Louis.

Randall has been helping Bullock raise her children since moving in, according to Us Weekly, and there's even talk of adding another child to their little family. Randall is already a dad to his daughter, who is college-aged.

"Bryan treats Sandra's children like his own. He really is a great father figure," an insider told E! News. "Sandra is the happiest she has ever been."

Friends and family who are close to the couple have said that Bullock has been so happy recently that they believe an engagement could be possible by the end of the year.
