Courteney Cox Wishes Jennifer Aniston 'Happy Birthday' With A Twinning Selfie

Anyone who is a fan of Friends loves to see that the cast members are all still friends now. It's the only way we get to relive the good old days — the '90s.

So, no one told you life was gonna be this way...

Your job's a joke, you're broke, your love life's DOA.

But at least Courteney Cox is out here throwing some major nostalgic vibes our way — posting photos of her and her gal pal, Rachel Green!

To celebrate Jennifer Aniston's birthday, Courteney shared a twinning selfie of the two of them on Instagram.

It's pretty much the greatest thing you'll see all week!

But it wasn't the first time she posted a selfie with Jen — or one of the cast members of "Friends" in general.

Last year on her birthday — long before Jen had Instagram, Courtney posted this photo of them.

"The world definitely got brighter the day this girl was born. Happy birthday sweetheart! I Love you!," she captioned it.

Once Jen finally made herself an IG profile in October, Courteney posted this, welcoming her to the wonderful world of social media.

"Hi Jen! Welcome to the social media world...it sucks. You’re gonna love it!," she wrote.

On her own birthday, she spent the day with Jennifer AND Lisa Kudrow.

"How lucky am I to celebrate my birthday with these two??? I love you girls. So much," she captioned this photo.

She has also recently shared reunion photos with the rest of her former castmates.

In October, the entire main cast got together for a reunion dinner at Courteney's house and took a few selfies. This was one of them!

"A rare night and I love it," she captioned it.

After having lunch with Matthew Perry in November, she posted a selfie of the two of them.

"Guess who I had lunch with today....I KNOW!! Could I BE any happier? #realfriends," she wrote.

She has also shared tons of throwback photos of her and her "Friends" family.

Like this one, for instance.

"The one where the six of us went to Vegas and no one knew we were F.R.I.E.N.D.S yet #tbt #beforeitaired #lovetheseguys," she wrote.

And this one:

"Celebrating a Thursday night 25 years ago. Thank you to all of our loyal fans across the world. You’ve certainly been there for us! I love these guys! @schwim @lisakudrow @mleblanc #seriouslyjen? #youtoomatthew #friends," she wrote (before Jen and Matthew had Instagram).

ANYWAY, you get it. Courtney Cox does not hold back when it comes to showing her "Friends" squad love on Instagram.

And today, Jennifer Aniston's birthday, was no different.

She shared this hilarious twinning selfie, holding — what looks to be, Jennifer's extension wefts on top of her head — wishing her a happy birthday.

I am loving this.

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

Jen showed her appreciation for the birthday shout-out by replying entirely in emojis.

It's 2020. Sometimes emojis can speak louder than words, amirite?

And of course, their friends and fans loved it too!

Can we actually make #TheJenChallenge a thing, please and thank you?

That would be the best thing the Internet could ever pull off.

Mindy Kaling chimed in, stating the obvious.

I absolutely love seeing this kind of support from one celebrity to another (or two). It's so adorable. Keep it up, y'all.

David Spade commented that Courteney and Jen managed to pull off twinning way better than expected, and I have to agree.
