Arrested Development scene-stealer Jeffrey Tambor became a father and a grandfather in the span of one week last month. The 60-year-old actor and wife Kasia, 35, welcomed son Gabriel Kasper on Dec. 10. Four days later, Tambor's daughter, Molly, gave birth to son Mason Jay Moore. And if that wasn't enough, li'l Mason was reportedly seen making googly eyes at Dora the Explorer, so expect an announcement from these two any day now. Congratulations to everyone!
