Hollywood actress Sandra Bullock has adopted a baby girl, five years after she adopted her son Louis.

RadarOnline.com has featured a source as saying that the Oscar-winning star has brought the baby to her home here, and has slowly been taking the newest member of her family out in public.

Bullock, 51, adopted Louis in New Orleans in 2010.

Another source added that "The Blind Side" actress was waiting for the right time, and with her relationship with photographer Bryan Randall going strong, she felt that the time was perfect to adopt a child.

"Sandra's made it quite clear to Bryan from the start that she's looking for a husband to raise kids with. She had the paperwork ready to adopt another child but really wanted to do it with the right man, and Bryan's been checking every box so far," the source said.

"Everyone knows how terrified she is of giving her heart away again, but Bryan's incredibly supportive, loving and a brilliant father figure for Louis. Sandra says he's perfect," the source added.

The couple is said to have been dating for several months before they went public with their romance in August.

Bullock's representative did not respond to a request for comment.
