Rising rapper Iggy Azalea has been forced to push back the release of her debut album to 2014 after signing up to support Beyonce in Australia.

The 23 year old's first studio record The New Classic was set to be released later this month (Oct13), but bosses at her label Island Def Jam insist she won't have time to promote it as she's opening for Beyonce when her The Mrs. Carter Show tour heads Down Under on 16 October.

Despite ending her run with the superstar by November (13), the release has been delayed until March (14) to allow for the festive holidays and the U.K.'s Brit awards in February (14).

Azalea says, "It's done, it's so depressing to say this but it's the beginning of March, it's so far away but I just have to accept that.

"It was supposed to be October but obviously I'm going on tour with Beyonce and they said I'm not allowed to put an album out while I'm on tour because I'll be trapped in Australia and I won't be able to do any Tv appearances and I thought that's fair enough, that's three weeks, and then they said, 'You can't put an album out around Christmas time, that's a bad time' and I said, 'What about January?'"

"(They said) 'Well nobody gets back off holidays and then it's the Brit Awards, you can't release an album, it's terrible for marketing', which brings me to February. The marketing team gets to control me unfortunately, I don't get to control that."
