Now Busted are officially "taking a break," Charlie Simpson has plenty of time to spend with his other band Fightstar.
But who are they and what are they all about?
Charlie plays guitar and sings in the four-piece band, and we're sure the rest of them are happy to soak up the free publicity the top popster gets them.
Joining Charlie on vocals and guitar is Alex Westaway, with Dan Haigh on bass
and Omar Abidi on drums.
Heavier than Busted
Fightstar are quite a heavy band, and they've been compared to bands like Biffy Clyro. We reckon they're a bit like Lostprophets. But probably with bigger eyebrows.
Charlie's looking rock!
Click on the link on the top of the page to hear a clip of them playing live.
You probably won't have seen them play live, as they've only had the chance to play little venues because of Charlie's commitment to Busted.
Reviews of the shows have been good, with the last gig sold out, and people queuing around the block.
So, if you like your music with a little bit of darkness, and you're not a Busted fan, give them a try!
Fightstar's first release, an EP called They Liked You Better When You Were Dead, is out on 28 February.
