Jennifer Aniston celebrated her 48th birthday in Los Cabos, Mexico. But it wasn't all fun and games.
The We're The Millers star was spotted poolside with her husband Justin Theroux, her Friends costar Courteney Cox, and her beau Johnny McDaid.
But apparently, Jen's hubby just can't seem to get along with Courteney's man! "They’ve never gotten along, so what Jen was thinking inviting Courteney and Johnny to her birthday is anyone’s guess," a source exclusively told OK!
"Johnny finds Justin pompous and self-obsessed, while he sees Johnny as beneath him. The whole trip — paid for by Jen’s travel connections, as usual — has been a disaster, and it’s wrecked her birthday.”
As the men were feuding, Jen showed off her toned physique in a light blue string bikini.
