‘Happy birthday to my sweet friend,’ wrote Reese, 44, who played Jennifer’s younger sister on the longtime show Friends.

‘Happy birthday to my #morningshow co-host!’ started the Emmy nominee.

‘From green sisters to news anchors, we can always find time to talk and laugh about everything under the sun.’

The Oscar winner then added: ‘Just one of the many reasons why I feel so lucky to meet you on and off the screen. Celebrating you today, my hysterical / loving / talented friend! @ jenniferaniston✨. ‘

‘What a joy to laugh and raise with my partner / sister / friend every day!’ added the energy producer.

Reese produced not only The Morning Show, but also Big Little Lies and Little Fires Everywhere under his Hello Sunshine banner.

Meanwhile, Jen’s ex, Justin, made noise on Thursday morning.

He said he loved Jen: ‘[heart you B!’ 

It is not known why The Leftovers star often calls her B as the letter is not in her initials – her middle name is Joanna.

The pair were married from 2015 until 2017 but managed to stay friendly after what Justin has previously called a ‘gentle separation.’

The Friends icon threw a glance over one shoulder as she climbed the stairs while modeling a long flowing overcoat.

They announced their split in February 2018 and a few months later Justin told the New York Times about how amicable the process had been.

‘The good news is that was probably the most – I’m choosing my words really carefully – it was kind of the most gentle separation, in that there was no animosity.’ 

The Tropic Thunder writer added: ‘In a weird way, just sort of navigating the inevitable perception of it is the exhausting part.’

Justin, who is three years younger than Jennifer, married her in Bel-Air in 2015 and they broke up about two years later.

Justin and Jennifer began dating in 2011, having worked together on the film Wanderlust. He had carried on a 14-year relationship with costume designer Heidi Bivens that collapsed in 2011. 

At the time, E! News claimed that Heidi had been, according to a friend of hers, ‘”straight-up dumped,”‘ though the report qualified: ‘Not to say it’s Aniston’s fault, maybe the timing was just terrible?’

‘Things were already over between him and Heidi before he got close to Jen,’ a source in Justin’s camp insisted to Page Six.

Heidi’s mother Marilyn spoke to Radar Online in 2016, claiming that Justin initially tried to persuade Heidi he and Jennifer were not an item.

Marilyn said: ‘Heidi told me what Justin had told her, that something was going to be written about him and Jennifer, that something was going on between them and he wanted her to know that it was nothing, there was nothing to it.’

Ultimately, Heidi discovered the rumors were true, ‘And my sweet Heidi she calls me and says: “Oh mommy.” I was going through cancer at the time. It was a time that hurt our family.’ Marilyn recalled.

Brad and Jennifer both won acting trophies last January at the SAG Awards – where he made a joke onstage about his failed marriages.

He vamped sarcastically that it had been ‘difficult’ to play a ‘guy who gets high, takes his shirt off and doesn’t get on with his wife’ in Once Upon A Time In Hollywood. 

The camera then cut to the audience where his Jennifer clapped at the joke and wore an expression of wry recognition.

She and Brad were spotted having a friendly conversation backstage – and as she walked away she placed a hand on his chest and he briefly held onto her wrist.
