Kate Hudson and her son, Ryder, left their hotel in NYC today. She's been in the Big Apple taking care of press for Something Borrowed, though the pregnant actress has also had time to hang out with friends. Kate caught a performance of The Book of Mormon and happened to be in the theater for the same show as Leonardo DiCaprio and Tobey Maguire. All eyes will be back on her, though, when she steps out on the red carpet for the premiere of her movie in LA tomorrow night, and she'll follow that up with an appearance on The Tonight Show on Wednesday. We talked to Kate and her Something Borrowed costar Colin Egglesfield about their chemistry in the film, and we'll get a chance to see it on the big screen when the movie comes out on Friday.
