Jennifer Aniston proved she was still great friends with former co-star Courteney Cox as she sealed the arrival of the actress’s 59th birthday with a kiss. 

The pair of A-listers rose to fame alongside one another on the set of Friends and have remained close as ever since the show came to an end in 2004.

On Thursday, Jennifer, 54, took the opportunity to celebrate Courteney’s final year of her fifties with an adorable tribute post on Instagram. 

Sharing a picture of the two locking lips for a playful smooch, the Murder Mystery star pressed upload on a vintage snap of her friend – and fans couldn’t get enough. 

Alongside the pucking photo, she added a collection of videos from the cult classic TV show and some other old memories from the friends’ history together. 

Jennifer ended the carousel with a stunning portrait of the two as they are now, fresh faced and happy as ever.

‘If you’ve been lucky enough to know her, you know how incredible she is. The biggest heart and most generous of humans. I love you, Cox-N-Hammer! Happy Birthday [sic].’ 

Fans rushed to the comment section to share their admiration for the two actresses and to individually wish Courteney a happy birthday.
