Jason Segel and Michelle Williams spent the weekend with her daughter, Matilda Ledger, in LA. The couple dressed up yesterday to take the 7-year-old on a special visit to Hollywood's Magic Castle, a club where magicians get together and show off their tricks. It's a favorite haunt of Jason's How I Met Your Mother costar, and magic enthusiast, Neil Patrick Harris. Jason, Michelle, and Matilda have been on the West Coast for the last few weeks while Jason and NPH work on their upcoming season. HIMYM returns to CBS on Sept. 24.
