The rocker is set to become a dad for the third time now his wife is expecting the couple's first child together.
Kelly told The Sun newspaper: ''Lots to celebrate recently - number one album, Welsh sport, and best of all we are thrilled to be expecting our first child.''
The 41-year-old musician tied the knot with Jakki back in 2013 after they started dating in 2008. He has kids Lolita, 10, and Misty, eight, with his former partner Becka Walters, who he split from shortly after Misty's birth in 2007.
The news of former MTV journalist Jakki's pregnancy comes weeks after the band topped the UK album charts once again with their ninth studio album 'Keep The Village Alive'.
Meanwhile, the 'Dakota' hitmaker recently revealed he has no interest in being ''famous'' and only got into music because he needed to be creative by writing songs and performing.
He said: ''I mean, at the end of the day it's a bloke writing poetry to music ... but I think people now, they look at the television and they think, 'I could do that', because they want what comes with it, but we didn't want to be famous really, that's the truth.''
