Armie Hammer and Elizabeth Chambers Expecting First Child

The Lone Ranger is getting some company.

Armie Hammer and his wife, journalist and TV host Elizabeth Chambers, are expecting their first child later this year, his rep confirms to PEOPLE exclusively. The couple just celebrated their four-year anniversary on May 22.

“I was always the guy who thought I’d never get married because [I thought], ‘There’s never going to be one woman worth giving up all the others,’” the actor, 27, told PEOPLE shortly after getting married. “But she knocked me off my feet.”

Chambers, 31, and Hammer, who will be seen next in Guy Ritchie‘s The Man From U.N.C.L.E. and begins shooting the independent dramatic thriller Mine later this month, also own and run Bird Bakery in San Antonio, Texas.
