Katherine Schwarzenegger thinks being a stepmother, as well as a mom, is a "blessing".
The 35-year-old author has daughters Lyla, five, and three-year-old Eloise, and son Ford, 11 months, with husband Chris Pratt and thinks it is "wonderful" that she also has a role to play in helping the Guardians of the Galaxy actor and his ex-wife Anna Faris raise their 13-year-old son Jack.
