Bridged not besided 🤦♂️
Yes there is a bridge, the nostr:npub18wn0jd3p7n6u3y7mc46p0hpx3cmtv9k3mu82rc0lhkg3rdyf590s3wshpx account is on the #Fediverse (please don't call it just Mastodon) and besided to Nostr.
Check out mostr.pub which is the bridge written by nostr:npub108pv4cg5ag52nq082kd5leu9ffrn2gdg6g4xdwatn73y36uzplmq9uyev6

Besided on Fediverse, got it! :-)
Anyway this is very cool, didn't even notice the .mostr.pub in the username.
