Jennifer Aniston and Justin Theroux are busy planning their wedding.
So who better to help than a happy pair of newlyweds and another engaged couple?
The vacationing stars were joined in Cabo San Lucas on Thursday by a clutch of their famous friends - British actress Emily Blunt and her husband John Krasinski and Jimmy Kimmel and his fiancée Molly McNearney.
It is safe to imagine the talk was of flowers and vows as the six couples spent the day tanning in the hot Mexican sun.
However, Jennifer did not appear to be wearing her massive eight-carat engagement ring, estimated to have cost Theroux $500,000.
Diffusing all pregnancy rumours, the blonde Friends star flaunted her toned stomach and natural born assets in a black string bikini and pink sarong as she relaxed.
Meanwhile, her 41-year-old beau eerily resembled Aniston's ex-husband Brad Pitt in Fight Club.
