McFly and Busted have teased possible plans to team up and form a supergroup.
The bands sent out a joint invitation inviting media to hear about their plans for 2014, according to Digital Spy.
The invitation was titled: "The ultimate pop supergroup is coming!" and went on to say that the bands would be unveiling their plans together at an event hosted by Emma Willis, wife of Busted star Matt Willis.
Matt and James Bourne from Busted will be at the announcement, as will members of McFly.
The bands have previously teamed up for McFly's 10th anniversary shows at the Royal Albert Hall earlier this year, where they performed together as McBusted and sang Busted hits Year 3000 and Air Hostess, as well as McFly's Shine A Light.
McFly release their new single Love Is On The Radio on November 24 and their upcoming album follows in spring 2014.
