Courteney Cox dresses up as Jennifer Aniston in birthday tribute

There really is no doubt that Jennifer Aniston is one of a kind.

The Friends star has been firmly in the spotlight of the public eye for well over 20 years now, but fans are just as adoring of her as they ever have been.

And lately, we've been treated to more Jen updates than ever before, after the actress joined Instagram, delighting her legions of fans with everything from flawless selfies to Nostalgic Friends reunion posts.

Jennifer Aniston watches her ex Brad Pitt deliver his Golden Globes speech:

Recently, Jen took to Instagram to welcome her friend and Friends co-star Matthew Perry to Instagram with a brilliant set of throwbacks featuring the pair. She wrote, "I'm shocked Matty is the last to join Instagram, considering he was a uh... umm....oh crap ??‍♀️ Oh! A computer processing TRANSPONSTER. #FBF"

And then, the 51-year-old, who just celebrated her birthday, posted a series of stunning snaps of herself from a recent photoshoot, writing;

"Thank you @interviewmag for this birthday surprise. I had no idea this would be coming out today. Feeling proud and honored to be celebrating with this cover. Thanks to the Interview team for celebrating women at every age... turns out 51 is pretty fun. And thanks to @nickkharamis, @melzy917, @alique_studio, @mrchrismcmillan, @gucciwestman — and my sister from another mister Sandy Bullock for talking to me about whatever the hell we were talking about. I love you so much."

And it's fair to say her co-star Courteney Cox was pretty excited by the photoshoot:

She wrote, "No matter how hard you might try... there’s only one Jennifer Aniston. Happy birthday my dear friend @jenniferaniston! I love you!♥️♥️♥️"
