Mariska Hargitay and Debra Messing spent Halloween together with the most epic hair-costumes

Move over Taylor Swift, there’s a new squad in town… well, it’s not really new, and they are more of a duo, but still, you should watch out!

The duo of Mariska Hargitay and Debra Messing spent Halloween together, and proved yet again that they are ultimate BFF goals. These two actresses have been friends forever, and with every year their bond grows deeper, so they’re pretty much the future of Swift’s squad, which is great.

On Monday, the BFFs dressed up as a Pink Lady (Hargitay) and Medusa (Messing) and partied the night away, taking many photos along the way — thank goodness.

"A HairRaising Night #Halloween @therealmariskahargitay," Messing captioned a hair-tastic photo of the two.

Hair raising indeed! Just look at Messing’s snake ‘do!

"Happy Halloween! Some traditions are just sacred. #PinkLady #Medusa #Halloween2016 @therealmariskahargitay Thank u @leahcmillinery 👏🏻👏🏻👏🏻" the former Will & Grace actress wrote on a closer shot of them.

This isn't the first Halloween the Law & Order: SVU and The Mysteries of Laura stars have spent dressing up together, but it was one of their better costume years.

Just kidding, every year is a good costume year for these two, who have made a tradition of spending the spooky holiday together.

Last year they dressed as Disney-Pixar characters and they nailed it.

Hargitay went all out with her Joy costume from Inside Out, while Messing played up her red hair and portrayed Darla from Finding Nemo.

In 2014 they also had a night of laughter and costume play as a Day of the Dead Bride (Hargitay) and Kit from A League of Their Own (Messing).

Could these two get any cuter?

Seriously if these two aren’t your #SquadGoals or #BestFriendGoals then we probably shouldn’t be friends!
