Baby, it’s cold outside – unless you’re Jennifer Aniston.
Also soaking up the sun on Saturday: Courteney Cox, also showing off her bikini figure. Other Cabo visitors include Howard Stern and wife Beth, and Jimmy Kimmel and his wife Molly McNearney.
Aniston and Theroux were snapped showing off their swimwear (and enviable bods). And, yes, the actress also flaunted her full head of hair.
Think the new year has a wedding in store for the happy couple?
