Is Kris Humphries practicing?

The newlywed hubby of reality TV star Kim Kardashian looked very comfortable in the role of surrogate dad as he carried his cutie-pie nephew Mason at the Central Zoo in New York on Thursday, and Breaking Celebrity News has the pics.

Mason’s mom Kourtney and sister Khloe were also on hand as the family checked out the sea lions, polar bears, lamas, and some sheep at the zoo.
