Sandra Bullock is concerned about her former stepdaughter, six-year-old Sunny James. According to the Chicago Sun-Times, Sandra received a call from her ex-husband, Jesse James, hours before he went public with the news of his engagement to 23-year-old tattoo artist Kat Von D. “Sandy is very concerned that all the turmoil in little Sunny’s young life is tough,” a longtime close associate told Sun-Times writer Bill Zwecker. “First there is that messy conflict between Jesse and Sunny’s mom, [porn star] Janine [Lindemulder], which originally also involved Sandy. Then, along comes the breakup of Sandy’s marriage to Jesse — and all the issues related to that — which Sunny didn’t really understand,’’ given her young age. “Now Jesse brings a new, very different kind of woman into Sunny’s life, who will be a very different kind of stepmother for Sunny. It’s hard to believe she will be as maternal and nurturing as Sandy is,” said the source, referring to Von D’s hard-edge image and reputation.
