The couple welcomed their first child together in January, who they named Bowie after the death of the late pop idol, David Bowie.
Take That are due to celebrate 25 years of their formation next year, and it's been revealed that Robbie Williams will be re-joining the popular group.
Howard married Katie, an illustrator, in January 2015, in a private ceremony in front of family and friends.
This will be Howard's second child with Katie, and his fourth child overall. He has two other daughters, Grace, aged 17, and Lola, aged 11. Both girls are rarely photographed.
Grace is from his relationship with Victoria Piddington, and Lola from his relationship with Marie-Christine Musswessels, whom he split from in 2009.
Hundreds of fans flocked to comment on the post, giving their congratulations to the couple.
'Aw, congratulations! Beautiful news xxxx' wrote one user.
'Wow fantastic, better to get the sleepless nights done together than have a gap and then start again lol' wrote another, while one added: 'Aww congratulations to you both. Bowie will love having a play mate!' wrote another.
Howard teased fans on Friday by tweeting, 'You'll never guess what?!'
Immediately people began to guess over the weekend, with a few people guessing right away.
'Katie's pregnant?' guessed one user.
'JASON'S BACK?!' exclaimed another.
'Take That album will be released today?' asked one hopeful fan.
Other people thought maybe he had another DJ gig, but the news was much happier!
