The singer shared his happy family news with fans on Twitter

Mikey shares his eldest child with his ex-girlfriend, Sharon Keane. He is also a father to Sienna Nicole, who he welcomed into the world with wife Karen Corradi in 2006. The couple have been married since 2004 having first met back in 1998 when Karen was a dancer on a Boyzone tour.

Mikey is very private when it comes to his family, but he did speak about his daughter Sienna in an interview back in 2013 and revealed she had just started to ask questions about his career.

"My older daughter Hannah is 17 and she certainly understands what it's all about. But it's interesting to see my little daughter Sienna," he said. "And it's now beginning to dawn on her that this is a slightly different type of job to the ones that her friends' dads do.

"I remember last year her asking me questions about my job. She said, 'Is Boyzone a famous thing, daddy?' Those kind of innocent questions, so she's just coming around to it now."
