Oritsé Williams and his wife Kazz are expecting their first child together.
The JLS singer has revealed his partner - who he married two years ago - is pregnant after a journey he says "tested them in ways he can't describe".
Alongside a black and white pregnancy photoshoot of the couple, he wrote: "Overwhelmed with emotion, love, and awe, words can’t express how I feel about my Queen, my soulmate, my hero, and stunning Mama Kazz.
"Her strength, her sacrifices, and everything she’s overcome to bring us to this point leave me in absolute wonder.
"This journey has tested us in ways I can’t describe, but her courage has shown me the true depths of love and resilience."
The 37-year-old star - who rose to fame with JLS on the UK version of 'The X Factor' in 2008 - explained they will be turning to their "little family bubble" during this next stage in their relationship.
He continued: "We’re embracing this sacred time together in our little family bubble.
"Our hearts are overflowing with gratitude for everyone who has stood by us and continues to surround us with true love and support.
"Your kindness carries us, and we are forever thankful to you."
Oritsé and Kazz got married in 2022 at Montega Bay in Jamaica, and he described it as "one of the most magical moments" of his life.
He previously wrote: "When we ran away, just the two of us together, just you and I and got married in Jamaica, it was one of the most magical moments in my entire life, but to be honest, I would’ve married you anywhere, because the magic is YOU.
"When I watched you walk down the pier isle, along the Caribbean Sea, in the stunning golden hour in your magnificent champaign dress, honestly you made me struggle to keep all composure, I knew I was so blessed, I felt like the luckiest man on earth from the moment you said YES."
