Iggy Azalea cops backlash over the name of her son as she leaves other fans confused with post about his citizenship: 'Weren't you Australian?'

Iggy Azalea has revealed her son Onyx Orion Kelly, six, is now an Australian citizen.

The singer, 36, who shares her only child with ex-partner American rapper Playboi Carti, posted the news to X on Thursday.

However, followers flocked to the comments to slam the musician over her son's name, while others were left confused about her own citizenship. 

Iggy shared a photo of the document which showed her son was made a citizen on May 23.

She captioned the post with green and yellow heart emojis, as well as a heart-face emoji.

Some fans took aim at the child's unique name. 

'Bro named her child after a Pokémon,' one person wrote, while another agreed: 'Really named your kid after a Pokémon huh? Grow up.'

Though another fan pointed out that Iggy likely named her son after the onyx stone. 

'The people in the comments thinking someone named their kid after a stupid Pokémon. Onyx is a STONE,' they commented. 

'Australians always showing they're a bunch of uncultured freaks I swear.' 

'With all due respect. What a f***ing s*** name,' someone else said of the name.

'WTF is an Onyx? Poor kid is gonna get picked on all thru primary and high school. Poor kid is gonna have 12yrs of hell. Why do that to him or her?' one wrote.

Meanwhile, other followers were left confused by the photo, with many questioning whether or not Iggy was born in Australia herself.

'Wait weren't you Australian to begin with?' one person asked, while another said: 'Weren't you born in Australia?'

Another fan quickly pointed out that the Australian citizenship document Iggy posted a photo of was for her son, not herself. 

'Australian citizenship law doesn't grant citizenship purely by descent in the same automatic way some countries do for children born overseas,' they added. 

It comes after Iggy recently made a return home to Australia. 

The Grammy-nominated hitmaker, who has lived in America for several years, returned to Australia over the Christmas and New Year's break. 

She was spotted behind the decks at Darlinghurst hotspot Noir while hosting the venue's pre-New Year's Eve bash for scores of Sydneysiders.

A video, uploaded to X by user Nate, showed the Fancy songstress beaming as she danced to the Beyoncé track Run The World (Girls).

Iggy looked to be having the time of her life, smiling broadly as she danced energetically with a retinue of fellow revellers on the stage.
