Singer-turned-fashion mogul Jessica Simpson is eager to stage a music comeback because her young children have no idea that mum is a pop star.

The Irresistible hitmaker took a step back from her chart career following the release of her holiday album Happy Christmas in 2010, and has spent the past few years focusing on her clothing and accessories lines while raising her 21-month-old daughter Maxwell Drew and seven-month-old son Ace Knute with her fiance, former American footballer Eric Johnson.

But the blonde beauty admits she would love to head back into a recording studio again so her family can share in her passion for music.

She tells U.S. breakfast show Good Morning America, "I want to sing again. I want my daughter to see me onstage. My fiance has never even watched me perform, which is crazy, but that's my passion, that's my love, it's everything that I am."
