Sandra Bullock has canceled another public appearance in the wake of her husband's cheating scandal -- she's scrapped plans to attend the upcoming Nickelodeon Kids' Choice Awards.
The Oscar-winning actress has been keeping a low profile since a U.S. tabloid exposed her husband's cheating last week, in which tattooed model Michelle McGee claimed to have had an affair with her husband Jesse James.
Several other women have also come forward with similar allegations.
Bullock canceled her trip to London for the U.K. premiere of "The Blind Side" after news of the scandal first broke, and subsequently scrapped her planned red carpet appearance in Berlin for the movie's official launch in Germany.
And now she's pulled out of the Kids' Choice Awards in Los Angeles on Saturday, which she had been expected to attend with her six-year-old stepdaughter Sunny -- James' daughter from a previous marriage.
But a rep for Bullock confirms to People.com that the actress will no longer be attending.
