135 Celebrities You Never Knew Were Friends

You may not have known it, but Jennifer Lopez and Leah Remini have been besties for quite some time—reasserting as much in the following Instagram that is pure #FriendshipGoals. "And we said...I will never eva leave you...Looove hanging w this one @leahremini #bestieday #jeleah #familia," JLo captioned the photo. 

Witherspoon and Kidman posed for a selfie after presenting together at the 2017 Golden Globes. "Loved presenting with my friend & co-star Nicole Kidman at the Golden Globes! Can't wait for y'all to see our show Big Little Lies on HBO," Witherspoon captioned the image on Twitter. 

J.Lo posted this Insta with a fellow amazing dancer, Jenna Dewan Tatum, to document their friendship and promote their upcoming show World of Dance.

Britney has always been considered to be solidly on Team NSYNC given the tight ties the singer shared with her '90s pop star peers, and one Justin Timberlake in particular, but your childhood as you knew it is about to get totally rocked. Britney Spears posted a photo on Instagram in which she's hugging A.J. McLean—as in A.J. of the Backstreet Boys—with the caption "Huge confession... biggest @backstreetboys fan! Tonight was truly a dream for me." It's okay Britney—we couldn't choose between NSYNC and Backstreet Boys either.

After befriending Beyoncé (next slide), Mariah Carey has unveiled yet another surprising celeb friendship: this time, with Will Ferrell. The comedian attended the Mariah #1 to Infinity show in Las Vegas, where the two had the chance to hang out backstage. MC documented the special moment on Instagram, writing: "Shake and bake !! Thank you for coming to my show last night !! #elf forever !!" The "Obsessed" singer even did Ferrell's makeup, which you can check out here.

Mariah Carey and Queen Bey hanging out together? That just might be too much for our diva-loving hearts to handle. The pair of living legends spent time together at an event for the HeartView Global Foundation in L.A.—which was graciously documented for us via MC's Instagram account. "Two girls, one cause," she captioned the pic.

Kourtney Kardashian was spotted out to dinner with none other than Justin Bieber. Is she taking a page from Scott Disick's dating playbook—or is she just befriending the much-younger pop star? Hmmm...

So this happened. Over the weekend, Kate Hudson hosted a chill game night—until Britney crashed (JK, Hudson totally gave her a ring) and the two dominated the night. Monopoly, Scrabble, Cards Against Humanity, no one was safe from these bombshell blondes.

The duo (who both share a history with Ben Affleck) hung out at the charity telethon event for Think It Up in Santa Monica, California, a charity aimed at improving education in America by inspiring public school students to turn their passions into projects.

We had no clue about this until 1) Kim posted a pic of them sipping on some pre-quarterfinals tea Monday and 2) we subsequently found out they've been friends/photographed together since 2006. Who knew?
