BACK TO SLIDE

Though the couple looks absolutely adorable in the photo, we totally can't stop staring at their jaw-dropping muscles! Britney has been putting in the work (b--ch!) in the gym and it's showing -- her ab muscles are out of control, and Sam's arm muscles (is he flexing?) have us completely floored. 

Sam, 24, and Brit Brit, 36, met in the fall of 2016 on the set of her "Slumber Party" music video, in which he played her love interest.

They've been dating ever since and frequently go on hikes, eat out at restaurants and go on vacation together with Spears' two sons. Could an engagement be in the cards this year?! Judging by Britney's latest post, we wouldn't be surprised.
