"So she's pulling the thing, like, 'Pull me outta here, it's time to go!'"
The 42-year-old star is delighted to have a new opportunity to be a "cool" dad because his sons Usher Jr., 12, and 11-year-old Naviyd - who he has with ex-wife Tameka Foster - are no longer easily impressed by him.
He said: "As they get older, I'm less cool of a dad. So now I'm starting this whole cycle over again and I'm kind of the apple of her eye right now."
And Usher's mom is also smitten with the new addition to the family - so much so that he's being "kicked out" of the room he stays in when he goes there.
He said: "My mom, with all of the kids, she gives them their own room.
"I'm like, 'Mom, you're kind of out of space, what are you gonna do?' She's like, 'Oh no no no no, she's gonna have her room. She's just gonna take your room.'
"She's kicking me out. I'm sleeping on the couch and Sovereign, she now has my old bedroom. But it's cool."
