Identical twins Lucas and Marcus Dobre are bona fide YouTube stars, with 6.3M+ subscribers to their channel. You may have seen them rapping and doing backflips in the viral video for their song “You Know You Lit,” which has over 35M views to date. But this year, the brothers ventured onto musical.ly to expand their social media empire. While very new to the app, they already have nearly 175K fans, who get to see their athletic dance routines to hits like OMI’s “Cheerleader” and the Shawn Mendes song “Stitches.” Of course, their acrobatic moves are indebted to their mom—a former Olympic gymnast—who sometimes appears and steals the show. Watch out, musers—here come the Dobres!
