The former JLS singer has taken to his Twitter account to reveal his girlfriend AJ Azari gave birth to a baby boy on Sunday (24.08.14) and the 27-year-old star admitted he watched ''in awe'' in the hospital.

He wrote: ''I watched in awe as @AJAzari gave birth to our 1st born son on Sunday 24th at 1.49am. He is my Treasure of life! x (sic)''
