Aniston and Theroux also vacationed in Mexico last December along with Kimmel and McNearney as well as Emily Blunt and John Krasinski.

Perhaps Blunt and Krasinski couldn't make it again this year since they are expecting their frist child. Recently, Theroux was seen dropping off Aniston at Blunt's baby shower on Dec. 14.

The couple, who got engaged in 2012, was photographed as they pulled up to the event in their black Mercedez-Benz. Aniston is said to have been carrying a small gift, wrapped in lilac paper with a white ribbon.

The Wanderlust costars also went Christmas tree shopping together earlier in December at Mr. Greentrees in West Hollywood to find the perfect one for the holiday.

"They looked at several trees," a source told E! News. "Jennifer seemed excited about a big noble fir and Justin agreed with her. You could see she took her choice very seriously and made sure to pick out the perfect tree for their new house."
