Twin sisters from Stuttgart, Germany, Lisa and Lena always seem to be smiling. At just 14 years old each, they have good reason to be so happy. After only beginning to post on musical.ly in December of 2015, it is impressive how far the blonde phenoms have come, building up over 15M fans and 650M+ hearts on the app in just one year. They often get featured, with videos of their choreographed lip syncs to songs like “Hit or Miss” by fellow muser @jacobsartorius racking up many millions of views. In 2016, the stylish sisters, who regularly wear matching outfits in their videos, launched their fashion line with clothes that match the duo’s cool, casual aesthetic.
