Union J say they can't wait for JJ to become a dad so they can have a little "mascot".
Band member JJ Hamblett announced last month that his girlfriend Caterina Lopez was pregnant.
Formed on the X Factor in 2012, Union J released their debut album on Monday.
The group described the moment they completed their album as "emotional".
