So will Katrin be a real YouTuber like Dagi? Now she has launched a challenge with her friend Anika Teller on her YouTube channel. And he seems to enjoy it! He also appeared in Liont’s video. And on Julienco’s Snapchat account, a girl could be briefly seen in the back seat of his car who looked like Katrin. Who knows, maybe Bibi will videotape him when the two are friends. Will Katrin open her own channel soon? We are excited!
