Union J eye Iggy Azlea and Little Mix duets

Union J say they would love to get a couple of babes – and possibly a baby – on to one of their singles.

Proud dad JJ Hamblett, 26, said his six-month-old son Princeton could add vocals to a track in a similar way to how Mariah Carey’s three-year-old twins sang on her latest album.

‘He doesn’t speak at the moment so it would be a bit difficult, but maybe the next album. That would be cool,’ Hamblett told me.

He added that the band – which includes Josh Cuthbert, 21, Jaymi Hensley, 24 and 20-year-old George Shelley – would love to draft in some female vocalists as well.

‘We’d love to do a song with Little Mix,’ the former X Factor star said, adding that Australian rap babe Iggy Azalea was also a target.

‘Me and George are huge fans of Iggy. We said eight months ago when she released Work that we would love to collaborate with her. And she just collaborated with Ariana Grande. She is so cool,’ he gushed.

It could become possible because Union J and Azalea are set to take to the stage at the Capital Summertime Ball in London’s Wembley Stadium on Saturday.

‘I’ve planned it already. I’m going to go backstage and put the idea out there. If you don’t ask, you’ll never know,’ he laughed.

Union J will perform their new single Tonight (We Live Forever), which is released in August, live on Saturday.

‘It’s about partying all night and being with your friends,’ Hamblett said of the song – adding that his young son with model girlfriend Caterina Lopez is not keeping him awake at night.

‘Do you know what? He sleeps all the way through. We are so lucky.’
