According to Masson, Sandra told the teacher, "Quite frankly, I'm glad Janine is in jail. She can go ruin someone else's life."Janine is trying to stop Jesse from taking Sunny to Texas.

After spending some down time in Texas, Sandra Bullock was spotted Saturday at an airport in Austin with baby Louis en route to Los Angeles.

The duo were on their way to California where Bullock, 45, attended a funeral for Rebecca Spikings-Goldsman, the wife of producer Akiva Goldsman who wrote the screenplay for the actress's 1996 film A Time to Kill.

Bullock, who last month stepped out publicly for the first time to attend some award shows in L.A., is gradually returning to public life – but is devoted to her role as a new mom.
