Is this the real reason Iggy Azalea cancelled her entire tour?

Iggy Azalea shocked fans last month when she suddenly announced that her two month long US arena tour was no more.

The tour, which was originally set to happen in April and May before being postponed until September, was cancelled entirely at the end of June. Iggy told fans of the news via Twitter, saying, "As u may know, the tour is cancelled. I'm so sad and sorry to let my fans down…we'll be back out on the road when the next album is done."

Considering the singer's career isn't exactly faltering – she won three Billboard Awards this year alone – many fans and friends have begun speculating about the real reason behind the cancellation, and if it could be due to the fact that Iggy is expecting her first child.

The Fancy hitmaker got engaged to her sports star boyfriend Nick Young recently after a year and a half together, and sources close to the star say her fiancé is keen for them to start a family as soon as possible.

"Nick made it very clear that if he and Iggy were going to marry, he wanted her to scale back on work," a source told OK! magazine. "Now her friends are buzzing that the real reason for the cancellation and the engagement is that Iggy’s pregnant."

With Nick wanting a traditional family unit, Iggy apparently wasn't "willing to gamble," the source says. "She’d take Nick over the tour any day."

So could a mini Iggy be on the way? We're not sure the world could handle it!
