Bullock's Onscreen Son Backs Adoption

The 45 year old won an Academy Award for her portrayal of Leigh Anne Tuohy - a wealthy woman who adopted a poor African-American teenager into her family and helped him forge a career as a football star - in The Blind Side.

Aaron, who played her onscreen son Michael Oher in the movie, admits Bullock's real life story reflects the plot of the film - and he's delighted his co-star has found happiness by welcoming little Louis into her life.

He tells People.com, "I am truly overjoyed for Sandra - what amazing news and so special that she has been able to keep this time private between her and the baby. Just as she played an exceptional mother in The Blind Side, her caring nature will make her an amazing mother to Louis!"
