Evanescence fans had to wait five years between 'The Open Door' and last year's self-titled album, and now singer Amy Lee is suggesting that fans may have to once again wait a while for album number four.

The band has done a lot of touring behind their self-titled effort, including the recent Carnival 0f Madness tour -- we were there at the Boston show. They are now preparing for upcoming South America and European runs.

Lee tells NME that Evanesence will probably take extended time off after this tour. "I'm really not sure what I'll do next," she explained. "At the end of any really long tour you need to get your head in order. I think at the end of the run we'll go on a break for a while and figure things out."

Lee says she doesn't have a problem with long gaps between albums. "Taking long breaks is seen as a bad thing, but I don't think it's a bad thing. People have the idea that you have to keep putting stuff out while people remember you. But I'd rather make something that's awesome and then make people remember again. I hope it doesn't take five years, but I don't want to put a timeline on it either."

Evanescence were recently nominated for an MTV Europe Music Award in the category of Best World Stage. The band faces some tough competition, with artists such as Justin Bieber, LMFAO, Snoop Dogg and Taylor Swift also getting nominations. The awards ceremony will be in Frankfurt, Germany on Nov. 11.
