Not to call Katina a stage mom, but her newest baby, a killer whale born Monday, already is getting into the family act at SeaWorld. The unnamed calf and its mother live in the same multimillion-gallon pool that SeaWorld Orlando uses for its signature Believe show at Shamu Stadium. Officials figured the show would be canceled for a few days but by 1 p.m. Tuesday -- less than 24 hours after the calf was born -- a modified show reopened with them.
