Olivia Wilde joined her brother, Charlie Cockburn, for a walk in NYC yesterday. The brother-sister duo brought Olivia's beloved dog, Paco, along for the outing. Olivia's family walk brought a change of pace for the actress, who's fresh off a California visit with her fiancé, Jason Sudeikis, that included a stop at Disneyland. Olivia will keep NYC walks on her schedule, though, since it was announced she will team up with Emma Stone to cohost the 20th annual Revlon Run/Walk For Women in the Big Apple on May 4. SNL star Jason may join Olivia for the five-kilometer race, while a pregnant Halle Berry is set to host the fundraiser for the seventh straight time in LA the following weekend on May 11.
