How Justin Theroux Paid Tribute to Wife Jennifer Aniston

See the actor's sweet note about his wife.

— -- Justin Theroux is new to Instagram, but he's already got the hang of hashtags.

The actor shared a photo of his wife, Jennifer Aniston, today, along with the hashtag #wcw — "Woman Crush Wednesday."

"#wcw #valentinored #xo," he wrote.

Theroux, 44, and Aniston, 46, were married this past summer in a surprise ceremony at their home. Jimmy Kimmel officiated the emotional ceremony, after which the newlyweds honeymooned with friends in Bora Bora.

"It’s fantastic," Theroux said of marriage during a September visit to "Good Morning America." "Something really does shift...in a wonderful way. And it sort of refocuses things."
