They may be there for each other when the rain starts to pour, but on Jennifer Aniston and Courteney Cox's Mexico vacation, the sun was shining and the former "Friends" costars were soaking it up in their bikinis.
Aniston, 44, and fiance Justin Theroux, 42, arrived in Cabo on a private jet on Friday, Dec. 27, with late-night host Jimmy Kimmel, his wife Molly McNearney, and friend Meilani Weiss.
The group was later joined on Saturday, Dec. 28 by Courteney Cox, 49, Howard Stern, and his wife Beth Stern. A source tells Us Weekly that the friends enjoyed the warm-weather tanning and swimming in the pool at the Casa Oliver -- a 16,000 square-foot home in the Puerto Los Cabos gated community, which costs around $9,500 a night.
The former costars have remained close since "Friends" ended in 2004. In 2010, Aniston appeared on Cox's TBS comedy "Cougar Town," and on Dec. 8, Cox attended Aniston's holiday party with Snow Patrol rocker Johnny McDaid.
