Jonathan Majors Wins Over TMZ Tour Bus ... Sings 'Happy Bday' to Fan!!!
Jonathan Majors isn't staying out of the spotlight amid his legal woes -- just ask the riders of the TMZ Tour ... who caught the dude in the flesh, and heard him flex his pipes!
Check out this video we got of JM from last week, when our tour guide spotted him driving next to our bus in the middle of a tour of Los Angeles. He was nice enough to chat with us and our guests for a bit ... and once he learned it was someone's birthday, he started singing.
Looks like Jon was riding solo here with his pup, but nonetheless ... he gave it his all.
