Sandra Bullock has reportedly adopted a second child

The 51-year-old actress - who adopted son Louis, now five, in 2010 - has reportedly expanded her family with a little girl and her boyfriend Bryan Randall, 49, is said to be supportive.

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.

"She had the paperwork ready to adopt another child but really wanted to do it with. Bryan's incredibly supportive, loving and a brilliant father figure. Sandra says he's perfect."

'Entertainment Tonight' has confirmed that Sandra has recently been seen out and about with a toddler, although she has yet to comment on the adoption reports.

Sandra previously gushed that being a mother makes her feel complete.

She said: "I was putting [Louis] to bed and told him that even when I'm old and gray and more wrinkly than I am now, I'll still love him and want to tuck him in. And he asked why I have wrinkles, and I said, 'Well, I hope some of them are from laughing so much.' And he touched my face and said, 'You're not old, you're just happy.'"
