Last August (14), the Livin' La Vida Loca hitmaker revealed he was keen to welcome a little girl into his brood in 2015, but the singer admits he has been too busy to fulfil his family plans.

He tells Australian radio show 3PM Pick Up, "I have to start trying for my little girl. I want to have a big family because kids are wonderful. I was able to choose my sons' gender thanks to in vitro fertilisation."

Martin had to juggle his coaching duties on The Voice Mexico with his touring commitments in late 2014, while he has been hitting the road to promote his new album, A Quien Quiera Escuchar, since the beginning of the year (15).

He also signed on as a judge for TV mogul Simon Cowell's new Univision show La Banda, which began auditions last month (Mar15).

Martin welcomed sons Matteo and Valentino via a surrogate in August, 2008.
