Justin Theroux joined Instagram this month, and since the actor signed up on the photo sharing site, his fans have been requesting for a selfie with his wife, Jennifer Aniston. Last week, "The Leftovers" star gave his followers a treat as he uploaded a photo with the "Friends" star to wish everyone a Merry Christmas.

In the shot, both he and his wife wore full ski gear as they posed for the camera. Theroux captioned it, "Happy Holidays & Merry Christmas!"

In the caption, he also mentioned his and Aniston's favorite charities as he encouraged fans to donate and share some of their blessings "if there's any Xmas cheddar leftover." He went on to name "a few of our favorite charities," which include St. Jude Children's Research Hospital, Best Friends Animal Society, Austin Pets Alive, North Shore Animal League, and Doctors Without Borders.

He also included talk show host Jimmy Kimmel on the list before adding, "I keeeeed! He's doing just fine."

Theroux previously posted a picture of Aniston, which shows her with her back to the camera while dressed in a long red gown. In his caption, he revealed that his wife is his "woman crush Wednesday" and included the hashtags #valentinored and #xo.

While Theroux and other celebrities such as Selena Gomez have posted pictures of the "Cake" actress in their Instagram accounts, Aniston herself does not have any social media accounts. Back in June, the actress tried her hand at social media when she took over Living Proof's Instagram account, as she is one of the owners of the beauty product company.

"I was so stressed out, sweating bullets," said the actress to People magazine about the experience. "It was too much pressure. For these Kardashians, it's a career!"

Aniston also said that social media seems to have an effect on how the younger generation communicates with their peers.

"Kids aren't speaking to each other anymore," she said. "Seeing other kids on their [phones] all the time, it makes me sad."
