The sextuplets' father, Jon Gosselin, was not present at his children's 13th birthday party, though he and ex-wife Kate do have shared custody of all eight kids. In an exclusive interview with ET last year, Jon claimed that Kate doesn't allow him to see his children as much as he'd like. "I can't even go to the school and contact them," he said. "It's just, like, I've been totally estranged from my kids."
