5 Seconds Of Summer's Ashton Irwin is celebrating his 22nd birthday today and producer John Feldmann shared a sweet message about the young drummer on Instagram earlier. 

He posted a photograph of himself smiling into the camera with Irwin and accompanied it with the following message: "Happy birthday brother love you so much. You're family to me and always will be. I'll see you soon!"

5SOS's bass player, Calum Hood, also posted a tweet about Irwin's birthday, writing: "Happy birthday to my brother. @ashton5sos here's to another lifetime with you!"

The band, meanwhile, recently teased their new music in a message that read "these demos are fire" and their new single 'Girls Talk Boys', which features on the new 'Ghostbusters' soundtrack, will drop on July 15. Referring to the song, 5SOS said: "The song is just fantastic and it also fits in with where the band’s sound is going. We are so excited for the fans to hear our new direction of music."
