They don't seem to be the best of friends while in Los Angeles (after all, she was married to his good pal Brad Pitt). But down in Mexico, they appear to be besties.

Us Weekly has reported that George Clooney had Jennifer Aniston over for dinner at his house inside the exclusive El Dorado gated community in Cabo San Lucas, Mexico on Sunday.

Other guests included the Friends star's fiance Justin Theroux and Clooney's new wife Amal Alamuddin as well as their friends Jimmy Kimmel, Emily Blunt, John Krasinski and Howard Stern.

An insider told the publication that '[Jennifer and George] brought Jimmy, Howard and John and their wives.'

The source added, 'George's chef cooked for everyone and they had a ton of wine and tequila. They stayed for hours and didn't get back to their house until very late.' No doubt the Ocean's Eleven actor's Casamigos Tequila was on hand.

And while everyone was celebrating and having a good time, the 45-year-old Cake actress discussed a little bit of business with George.

'They are talking about making a movie in Cabo,' the source continued. 'Jennifer is really excited about it and wants to do it.'

On Monday, the former Friends star was seen enjoying the warm rays with her 43-year-old actor fiance Justin and all the married couples minus George and Amal.

For the last few years, Jennifer and her A-list pals have been retreating to Cabo San Lucas around New Year's Eve. It was also the same place she vacationed with ex-husband Pitt in 2002.

George also vacations in Cabo every year with his buddies, but this year was the first time as a married man.

The Monuments Men star has been spending the holidays in Mexico with his barrister spouse Amal just two months after the couple's romantic wedding in Italy.

The newlyweds joined the actor's BFF Rande Gerber and his model wife Cindy Crawford and have been spotted enjoying each other's company since December 23.
