The six-piece will now play at the venue on 19th April, as well as their originally scheduled date on 18th April.
Tickets for that date are also ready close to selling out with only a limited number remaining.
And as a result, the band have now added the second Nottingham date to their schedule.
Now, armed with an eponymously-titled debut album, and a new single, Air Guitar, the amalgamation of Busted and McFly are playing a number of arena dates next year.
Air Guitar is released on 23rd November with their debut album, McBusted, following on 1st December.
Tickets for their Nottingham gigs are £46.48 and available from the box office on 0843 3733000 or online at www.capitalfmarena.com/online/mcbusted
