Christina Aguilera's son would rather be playing Fortnite than be backstage at her tour.

The 'Genie in a Bottle' hitmaker has confessed that her 10-year-old son Max is more interested about playing the sandbox video game than seeing her mom perform her Liberation Tour at Radio City Music Hall, New York City.

Speaking to the crowd, she said: ''My son is backstage tonight. He just flew in. The last time I was on tour, I was pregnant with my son. And now he's back here tonight. Tonight wasn't easy getting here. Summer was not happy about tonight's performance at all, but she finally went to bed. My 4 year old is dying for me to be off stage so she can spend time with me and my oldest is like, 'Can I go home and play Fortnite now?' I'm like, 'Ugh thanks.'''

Meanwhile, Christina previously confessed she took a decade off from touring to be with her family - her son Max and her daughter Summer Rain, four.

She said: ''Being a mom is really important to me and I'm a very hands-on mom. I never want them to feel that they live in my shadow or that they are not important. I don't wanna be that kind of mom, so I took some time off for them. But momma needs to go back to what she's meant to do ... The last time I was on tour, I was pregnant with my son onstage, so I was about to give birth. At a certain point I had to stop touring for safety reasons. You get to a certain point [where] you have to stop. Ever since then I was like, 'How do people do this with kids and touring?' But, you know, it's time for mama to get back to what I was born to do.''
