Jennifer Aniston and Justin Theroux cosied up at a friend's wedding over the weekend, as they reportedly put in place the final preparations for their own upcoming nuptials.
The pair attended the ceremony of actress Lake Bell Justin Theroux's friend Scott Campbell in New Orleans on Saturday, with Jen's beau even acting as an usher during the proceedings.
Sources say Theroux flew into the Big Easy on Thursday, and spent time 'having dinner and socialising' with the groom, while Jennifer Aniston arrived on a private jet shortly before the ceremony.
Onlookers say the actress was met by security at the airport, and hopped straight off her private plane into a car, which went directly to the Marigny Opera House venue, just in time for a 7pm start.
Afterwards, sources reveal Jennifer Aniston hung out with fellow A-lister Cameron Diaz, who according to E! News, was shadowed by security at all times and kept her sunglasses on 'a lot'.
Meanwhile, Eva Longoria and Kate Bosworth were also in attendance.
Jennifer Aniston and Justin Theroux's wedding weekend comes as it's rumoured they're putting the finishing touches to plans for their own nuptials.
Reports suggest the pair could marry at home on their newly renovated $21million estate in Los Angeles this sumer.
The 44-year-old actress and her fiance, 41, have been overseeing extensive updates on the 8,500-square-foot plot which now features a separate guest house, swimmers' pool, a vineyard, wine cellar, and a projection room.
