Sandra Bullock rattled by Michael Oher's revelations

Bullock has had a difficult month so far due to the fallout from the shocking Michael Oher lawsuit, which has left her "heartbroken and upset" about the revelations.

According to court documents, Sean and Leigh Anne Tuohy, the parents of Oher, the 37-year-old offensive tackle who served as the inspiration for 'The Blind Side', never actually adopted him.

Bullock famously played Leigh Anne Tuohy in the hit 2009 film.

A source told Daily Mail, “There was so much hard work put into the film that they all thought was the truth and now that has been questioned, it just upsets Sandra to no end that a time in her life was so special, is now shadowed with a completely different perspective."
