Bow Wow will be joining Omarion for his Millennium 2020 tour, which follows up his B2K featured Millennium tour.

The last time Bow and Omarion hit the road together was in support of their 2007 joint album Face Off.

The pair did Rap Radar's podcast to promote their latest excursion and during the chat they remembered the time JAY Z saw them play during their Face Off tour only to leave after one song, their cover of the JAY, R. Kelly track "Best of Both Worlds".

"[JAY Z] heard about it and said 'They perform Best of Both Worlds. That's the first song that they come out on,'" Bow Wow recalled "I do [Hov's] verse, Omarion does Kellz' part. So Hov comes to the Garden, stands in the tunnel, watches the intro and me and O are hyped. By the time the song was off, I looked in the tunnel, Hov was gone. He came to watch that one piece, there were twenty thousand in that motherf8cker, he saw that sh!t and then got in the car and drove off."
