Reese Witherspoon was showered with birthday wishes on Friday when the Legally Blonde actress turned 48 years old.

One of the most heartwarming testimonials came from her longtime pal Jennifer Aniston, whom she has known for over 20 years.

During the height of Jennifer’s stardom as Rachel on Friends, Reese did a few guest appearances as the character’s spoiled sister Jill.

In recent years, the pair have been playing opposite each other as seething professional rivals on the Apple TV+ series The Morning Show.

But when Jennifer fired up her Insta Stories for her birthday tribute to Reese, the onscreen enmity was replaced with real-life gushing affection.

‘Happy birthday to my sister @reesewitherspoon,’ Jennifer wrote over a clip of Jill haughtily confronting Rachel on Friends all those years ago.

‘Love you so much, you ray of sunshine,’ she effervesced over a picture of Reese beaming while cradling her French bulldog Minnie Pearl.

She hailed Reese as ‘the ultimate collaborator…’ as well as a ‘Co-anchor,’ ‘Partner,’ ‘and friend’ – with each title accompanied by a charming throwback snap.

One of the pictures showed Jennifer and Reese performing in front of a green screen during the shoot of The Morning Show.

Another was a flashback snap of the two women drinking champagne at the 2020 Golden Globes with The Morning Show showrunner Kristin Hahn.

Jennifer first shared the Golden Globes picture with the public all the way back in 2020 – and relayed the cheeky story behind it.

‘Reese!? This is one of the many reasons I love you,’ wrote the Horrible Bosses actress. ‘We ran out of water at our table so naturally, she asked Jay Z and Beyoncé for a glass of their champagne.’

As Reese celebrated her 48th birthday this Friday, she was treated to an outpouring of affection from the boldface names in her life.
