Jennifer Anniston, 50, appeared to be in high spirits as she partied the night away during her birthday celebrations with her ex-husband Brad Pitt, 55, seemingly making an appearance. But now the former Friends star’s former husband Justin Theroux, 47, is showing some love to her in a sweet message he posted on Instagram. In view of his 642,000 Instagram followers, the actor posted a black and white snap of Jennifer raising an animal horn plaque above her head, showing off her toned arms in a black vest top. He captioned the post: “Happy Birthday to this fierce Woman. Fiercely loving. Fiercely kind. ….and fiercely funny [love heart emoji] you B.”

Fans were delighted with the heartwarming post as many flocked to comment, as one person wrote: “Beautiful tribute.”

A second person replied: “I think I passed out for a couple of seconds.”

While a third person commented: “AHHH OMG I JUST DIEDDD.”(sic)

It comes after the pair announced their divorce in 2018 after two years of marriage.

However, it is unclear if Jennifer got the message as the Hollywood star does not have an Instagram account.

Meanwhile, the beauty stripped down to nothing but some plain denim jeans in a photoshoot with her hairdresser Chris McMillan.

In a series of monochrome photos, he took to his Instagram page to honour the actress in a special 50th birthday tribute.

In view of his 234,000 Instagram followers, the heavily tattooed hairdresser can be seen holding Jen in a warm embrace as the pair go topless.

The hairdresser is beaming and has one hand over Jennifer’s famous hair, and the other clasped around her waist.

The actress is wearing just a pair of jeans as she smiles coyly at the camera, with her right arm skirting across Chris’ hip.

He captioned the post: “Happy Birthday Jen. To my friend. To my inspiration. To my teacher. I love this girl to the moon and stars.”

The tributes did not stop there as he posted more photos of the Hollywood starlet as she modelled topless in various other garments, including a hat, Calvin Klein briefs and and an unbuttoned white shirt.

Fans were in awe of the stunning photos, as they bombarded the comment section, with one person who replied: “Beautiful Connection! Thanks for sharing it with the rest of us.”

Another person gushed: “I LOVE this picture!!! I LOVE this friendship!!! I LOVE EVERYTHING about this!!!”

A third person replied: “Beautiful picture! Beautiful friendship! What’s not to love about this gorgeous and amazing woman?”

Jennifer previously touched on her previous marriages to Brad and Justin in an interview with ELLE last year.

“My marriages, they’ve been very successful, in [my] personal opinion,” she said.

“And when they came to an end, it was a choice that was made because we chose to be happy, and sometimes happiness didn’t exist within that arrangement anymore.”
