Union J joined Capital FM for an exclusive webchat on 14th May.
The former X Factor stars took questions from fans on everything from their debut single 'Carry You' to life on the music reality show.
Union J's debut single 'Carry You' will be released on 2nd June.
The four-piece are also among the performers at this year's Capital FM Summertime Ball.
The boys will join the likes of Robbie Williams, Taylor Swift and The Wanted when they take to the stage at Wembley Stadium on 9th June.
The event will also be hosted by Justin Timberlake and features the biggest ever line-up.
Union J: "We would absolutely like to work with Jason Derulo."
George: "'What About US' by The Saturdays because we did actually start doing it and it sounded amazing."
"Jaymi is mum. When we went to Vegas he was the one who carried the passports so he kind of looked after us."
George: "Demi Levato. I love her."
JJ: "Super JJ. No, Captain JJ."
