In January, Howard and Katie welcomed baby Bowie into the world and they are now looking forward to expanding their brood further.
Howard, who has two daughters - Grace and Lola - from previous relationships, announced his wife's pregnancy on Twitter and joked with fans about the continuation of "sleepless nights" that he will be enduring!
He tweeted: "Guess what? Me and katie are happy to announce we will have our 2nd child in Feb. Yay! No more sleep for another 2 years!"
Howard and Katie married in January 2015 in a top secret ceremony and lavish reception. Their wedding took place over two days and guests included Take That bandmates Gary Barlow, Mark Owen and Jason Orange, who quit the group in September 2014.
Fans have flocked to Twitter to congratulate Howard and Katie on their latest news, with one tweeting: "Aw massive congratulations to you both, what lovely news!" Another joked: "If you ever need a babysitter, I'm available at all times!"
Meanwhile, Howard isn't the only 90s pop star to announce baby news. Former Spice Girl Geri Horner (née Halliwell) has also confirmed she is expecting her second child.
