Britney Spears Posted a Video Dancing to Justin Timberlake's Song

She even tagged him.

Tagging an ex in an Instagram post? Could go in a lot of directions. Dancing to his song, posting to Instagram, and tagging him? Iconic.

Britney Spears took to Instagram to share yet another dancing video (in front of her Christmas tree that is still up, might we add). This time, her song of choice was "Holy Grail" by ex Justin Timberlake and Jay Z.

"Danced in my black [turtle] neck last week to HOLY GRAIL !!!!" the "Hit Me Baby One More Time" singer wrote. "I KNOW ... turtle necks are SO ME !!!! @justintimberlake"

The video featured the "Toxic" singer wearing a black turtle neck crop top and plaid what appears to be Soffe shorts as she twirls and shows off some new dance moves.

The two '90s and early '00s pop icons began dating back in '99 after she opened for his band NSYNC. They dated for three blissful years of red carpet appearances, legendary matching denim outfits, and many a TRL spottings before calling it quits in March 2002 (a sad day for early aughts teens).
