'She's a nut! She's a little crazy!' Adam Lambert calls out 'loose cannon' Iggy Azalea AGAIN for her behaviour on The X Factor... and implies she isn't looking after her groups properly

Both Guy Sebastian and Adam Lambert have already stated in interviews that Iggy Azalea's behaviour behind the scenes of The X Factor has been questionable.

And on Monday, Lambert was back at it again during an appearance on Nova 969's Fitzy & Wippa show, where he called out the 'crazy' rapper for being a diva.

'She's just a tough nut to crack... and she is a nut! She's a little crazy,' said the handsome 34-year-old.

'She's such a diva!' The X Factor's Adam Lambert didn't hold back when it came to exposing Iggy Azalea on an Australian radio show on Monday

He continued: 'Her and I get along really well one-on-one, but then I see some of the shenanigans she pulls with other people and I'm like 'GIRL! Pull it together!'

'She's such a diva!'

The glamorous rock star then caused host Fitzy to burst into laughter after he threw some hilarious shade at Iggy, saying: 'Your team is super important, maybe the people you're mentoring might be kind of important - just a thought!'

'Her and I get along really well one-on-one, but then I see some of the shenanigans she pulls with other people and I'm like ' GIRL! Pull it together!' said Lambert

'She's just a tough nut to crack... and she is a nut! She's a little crazy:' The singer didn't hold back when it came to spilling the tea about his fellow judge

He then told a story about how one of the groups Iggy is supposed to be mentoring came to his dressing room, off camera, to seek advice from him on what they should do - implying that the Mullumbimby-born bombshell isn't doing her job properly.

'I probably shouldn't be saying this,' he laughed.

The radio duo pressed Lambert for more dirt on the Team rapper.

'I probably shouldn't be saying this,' laughed Adam as he revealed more dirt on Iggy

'Your team is super important, maybe the people you're mentoring might be kind of important - just a thought!' said the shady superstar 

'She's a loose cannon,' he said. 'It's hard to kind of predict what she's gonna say. If she's going to show up, or if she's going to listen.'

This isn't the first time that the American Idol runner-up has publicly exposed Iggy's antics.

During an appearance on Sunrise last week, the sassy singer opened up about the apple-bottomed rapper's tardiness.

'She's a loose cannon. It's hard to kind of predict what she's gonna say. If she's going to show up, or if she's going to listen,' Adam finished.

'She shows up late, you never know what you're going to get with her. It is never boring. I will tell you that,' he told hosts Samantha Armytage and Mike Amor. 

Fellow X Factor judge Guy Sebastian has also called out Iggy.

'She isn't the easiest person to work with,' the former Australian Idol winner told NW last month. 

And during a radio interview with KIIS FM's Kyle & Jackie 'O' show, the 35-year-old singer also complained about Iggy's lack of punctuality on set.

'Iggy is an hour, two, three hours late, and Adam and I will just cop it,' he confessed. 

'She isn't the easiest person to work with:' Another X Factor judge, Guy Sebastian, has also backed Adam's statements by slamming 'tardy' Iggy in the press
