Sandra Bullock Angry after Adopting New Baby?

By all account, this should be one of the happiest times in Sandra Bullock's life with her new boyfriend, Bryan Randall, and having just adopted a brand new daughter, but word has it that just isn't the case. According to the latest gossip news updates, the excitement over her new baby didn't carry over into the Our Brand Is Crisis star's recent appearance at the Toronto International Film Festival. Word has it the it that the 51-year-old Hollywood icon acted like an irritable diva at the event -- berating the crew working for her -- before storming out ahead of schedule.

She may have a reputation for being America's sweetheart, but it's said that Sandra Bullock hardly lived up to expectations during a recent press event at this year's Toronto International Film Festival.

One eyewitness source in the latest December 28, issue of Star magazine claims that Sandra absolutely acted like a holy terror from start to finish, while promoting her latest movie up north:

"She walked in with a scowl on her face, and the only time she smiled was when the camera started rolling.

"She was complaining about the wrinkles on her neck and berating the cameraman over the lighting, saying he was making her look bad.

According to the informant, Sandy topped things off by storming out before she was supposed to -- not that anyone dared tried to stop her:

"Everyone breathed a sigh of relief when she left.

"She didn't say goodbye or thank you...She just walked out."

As exciting as that all sounds, however, Gossip Cop's supposed insider assured the magazine that nothing like that "ever happened", despite Star's fantastical report to the contrary.

What do you think of Star's claims that Sandra Bullock is not what she appears to be?

Is it really possible that Sandy has been putting on a front for the past 30-years?

Or, is it just another case of the tabloids trying to make a buck by smearing a celebrity's good name?
