PICTURE EXCLUSIVE: Great at 48! Jennifer Aniston flaunts ʙικιɴι body during birthday trip to Mexico with a VERY toned Justin Theroux

Jennifer Aniston turned 48-years-old on Saturday and the Friends vet celebrated with a trip to Los Cabos, Mexico.

Over the weekend the blonde beauty was seen showing off her incredible ʙικιɴι body as she relaxed by the pool of her rental.

Also with the Horrible Bosses actress was her very toned husband Justin Theroux, who looked like he was in the best shape of his life, as well as her best friend Courteney Cox and her beau Johnny McDaid, 40.

Aniston looked at ease as she was seen in the backyard of her villa layering on sunscreen.

 

The ex-wife of Brad Piit was first seen in a light blue two piece that consisted of a triangle top with spaghetti straps and simple bottoms.

The perky LA native also wore her hair down in loose waves.

And the Vogue cover vet made sure to accessorize well with a dark pair of Ray-Ban aviators, her shiny gold wedding band and a bottle of Smart Water, which she just happens to be the spokesperson for.

At one point the looker, who lost her mother Nancy Dow last year after a long illness, raised her arm to say hello to a friend.

And there was a brief moment when her Leftovers star husband looked out at the water which gave a perfect view of his extremely toned abs and pecs.

The dark-haired TV star added a Supreme camo cap and board shirts.

A yellow gold necklace with several pendants, one of which looks to be a gun, hung from around the Mulholland Drive star’s neck.

The New York City native has said in the past that he works out for his health and state of mind.

And it’s obvious that he has not slacked as he heads toward his fifties.

Often Theroux covers up his physique with dark motorcycle attire that include leather jeackets, jeans and boots.

Later, the knockout wore a black ʙικιɴι top that seemed like it was on the verge of a wardrobe malfunction.

When the box-office babe leaned over to chat to a pal, it looked as if she might expose too much.

But the always elegant Aniston kept it together. Too bad she covered up her lean legs with a towel.

 

Also by the pool was her longtime Cox, who she worked with for a decade on the sitcom Friends.

Courteney looked toned as well as she showed off sculpted arms and ribbed abs in a black ʙικιɴι with white piping.

She was engaged to Snow Patrol singer McDaid for about a year and then they called it off, citing the distance – he lives in Ireland while she resides in LA with her daughter Coco Arquette from ex David Arquette.

But the two got back together and now travel often to see each other.
