Justin Theroux Explains How He Buys Birthday Gifts for Jennifer Aniston

Actor Justin Theroux is revealing details on wife Jennifer Aniston's 48th birthday getaway.

The couple soaked up the sun in Cabo with Jen's former “Friends” co-star Courteney Cox and her BF Johnny McDaid. Justin told “Extra” about the “lovely” bash at CinemaCon on Wednesday, calling it a “little time in the sun — perfect.”

Finding the perfect gift for his wife can be a challenge. Justin shared, “It's always a critical moment, 'cause I have Christmas, her birthday and Valentine's Day in pretty short order, so I start shopping in November.” The 45-year-old opted for something fun, commenting, “It's usually something that is the easiest thing in the world — a snuggie. Or I'll figure out something like that, something fun. I've given up on mass pieces of jewelry or clothes. She's got all that. It's usually something like an amazing pair of flip-flops, something she can get cozy with.”

The actor is getting ready to give fans an animated treat with “The Lego Ninjago Movie” as the voice of Garmadon. “It's the best part of the job,” he said. “You get to do it, it's low pressure, you shout out your lines, you laugh a lot.”
