Jason Segel held hands with Matilda Ledger yesterday while on a stroll in Brooklyn with her nanny. The duo shared smiles and Matilda even showed off some dance moves. It seems Jason's keeping an eye on his girlfriend's daughter for the time being. Michelle's expected in San Diego today to take part in a Comic-Con press event for her upcoming film Oz: The Great and Powerful. Michelle will attend alongside her costar Mila Kunis — we're on the scene in Southern California, so make sure to check back for frequent updates. Jason just wrapped up a period of his own business travel. He was in Europe last month doing an overseas tour for his film The Five-Year Engagement. He made stops in Dublin, Hamburg, and London before returning to NYC and his girls. Michelle Williams and Jason Segel spent time together in her neighborhood, and he also supported her at her Big Apple premiere of Take This Waltz.
