Revealed: Iggy Azalea 'discovered Nick Young's ex-girlfriend is four months pregnant with his child' before calling off #engagement

Iggy Azalea broke things off with Nick Young because he is expecting a second child with his ex-girlfriend, new reports are claiming.

The singer ended her engagement to the NBA player earlier this month and announced at the time that she couldn't re-build her trust in Young after cheating rumours swirled earlier this year.

But it seems that there is much more to the story now that sources are claiming Young, 31, cheated on the Aussie star with his baby mama Keonna Green.

'Nick waited until Keonna was four months pregnant to tell Iggy the news,' an insider told Life & Style.

They added that he told Iggy 'he was drunk and had a lapse in judgment.'

'He said it was a one-night stand and will never happen again,' the insider explained before revealing Young is expecting another boy with the mother of his four-year-old son Nick Jr.

'This is something she can’t ignore, and it ruined their future together.' a source said.

Life & Style claim they approached Keonna last week where she confirmed the pregnancy was an accident but refused to comment further.
