Barclay Beales, Chris Leonard, Casey Johnson, Jake Sims, James Graham, Charlie Jones, Reece Bibby and Tom Mann are holding a big bash at London's O2 Shepherd's Bush Empire, 21 June.
Their first debut single 'Love Me So' is released the very same day, and if you've seen the music video, you already know how good it is!
The former X Factor contestants revealed the news on Twitter, saying: "Proud to announce #LOVEMESO LAUNCH PARTY Tkts for you guys on sale soon!!"
Tickets cost £17.50 and go on general sale tomorrow (22 May) at 9am.
'Love Me So' is penned by band member Tom. He told the Southern Daily Echo that the track is being "released in association with Sony in a one-track deal, so we hope it will do well and more will follow!"
Tom added: "For me it is a massive achievement because I love song-writing. I'm over the moon; it's a massive honour and all the boys love it and for all of us to be on the same page about it is great. I didn't even push for it."
