Sandra Bullock has expanded her family! The 51-year-old Oscar-winning actress has adopted a new infant daughter - more than five years after adopting her five-year-old son, Louis, in New Orleans, according to RadarOnline

Bullock has reportedly already finalized the adoption and moved her daughter into her Los Angeles home. The report added that the "Blind Side" actress has slowly been taking her daughter out in public. 

Apparently, it's no coincidence that the adoption news comes days after reports claimed that Bullock and her new boyfriend Bryan Randall have moved in together. Bullock has been waiting to adopt again; however the actress wanted to settle down first, a source told RadarOnline.

"Sandra's made it quite clear to Bryan from the start that she's looking for a husband to raise kids with," the source said. "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 continued: "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."

Things have been moving fast between the two, with a source saying that Bullock and Randall, an LA photographer, are already "in love," according to E! News. The two are reportedly in this relationship for the long haul.

"Sandra and Bryan have a very busy schedule, so the time they do have, they are with each other. They have discussed spending the rest of their life together, but taking day by day and just enjoying each other," the source said, adding, "Sandra couldn't ask for a better guy. They have a great dialogue when together and say 'I love you' very fluidly."

Bullock and Randall were reportedly dating for several months before they went public with their romance in August. Randall reportedly escorted Bullock to Jennifer Aniston and Justin Theroux's wedding this past summer.

Bullock was previously married to motorbike customizer Jesse James. The two split in 2010 after five years of marriage following James' confession that he had cheated on Bullock with several other women. In a new interview with In Depth With Graham Bensinger, the "Monster Garage" host, 46, took full  responsibility for the end of his marriage and still bitter about losing Louis, whom he and Bullock had planned to adopt together prior to their split. Bullock finalized the adoption alone. 

"The painful part was about Louis, who we adopted," James said. "As bad as stuff was between us, we adopted a kid and things got kind of good for a little while and we had that kid to focus on, and, boom, it was over in 24 hours - gone, done."
