The McFly and Busted supergroup, who will perform at gigs across the UK next year, are overwhelmed by the reaction to the announcement and their first joint gig during Friday's 'Children In Need' show.
They will play four additional shows in Liverpool, Birmingham, Nottingham and Newcastle in May next year, after already adding a further six dates to the tour recently.
McFly frontman Tom has also hinted that the supergroup might write music together, saying: "For now it's just the tour, but if we come up with something and write some songs that we think are incredible, then we'll release it."
James Bourne and Matt Willis will represent Busted - original lead singer Charlie Simpson will not be part of tour - while all the McFly boys, Tom Fletcher, Danny Jones, Dougie Poynter and Harry Judd, will take part.
The two bands previously teamed up at McFly's 10th anniversary show in September, when Busted joined the boys on stage at London's Royal Albert Hall.
The musicians performed the classic Busted hits 'Year 3000' and 'Air Hostess', before playing McFly's 'Shine A Light'.
McBusted will kick off their live dates on Friday, April 18 at Glasgow's SSE Hydro.
Charlie quit Busted in 2004 to form rock band Fightstar and is currently pursuing a solo career. Since leaving the pop group, Charlie has sought to distance himself from Busted.
