Much like The Sisterhood of the Traveling Pants, the ladies of Teen Mom are fast-friends who always have each other's back — and may or may not share a pair of metaphorical traveling pants. Basically, these gals are BFFs for life (minus Farrah Abraham who everyone seems to feel iffy about), and you better believe they stay in contact!

Now that TM's most notorious starlet, Amber Portwood, has joined Twitter, she can finally get back in touch with her sister from another mister, Maci Bookout. While these gals lead very different lives (and live in different states), they became close while filming Teen Mom After Show specials, and doing promotional work for MTV!

When a fan posted flashback photo of Maci and Amber in New York City, both ladies lept at the opportunity to walk down memory lane — and they reconnected in the process.

"Oh my gah i remember this!" Maci tweeted, to which Amber responded "That was so long ago! We had fun that night though <3"

But wait, there's more! "Hahahaha ive never laughed so hard .. miss u!" Maci tweeted her co-star, to which Amber replied "Miss you too babe we'll be seeing eachother again! Sending love <3"

We're so happy that Amber and Maci are back to being besties! And who knows, maybe they'll end up staring in a Teen Mom reboot together sometime soon...sob, their 'ship will never sink!
