Sinead O'connor is convinced her youngest son will follow in her musical footsteps because he sneaks out of bed at night to play the guitar.

The Nothing Compares 2 U hitmaker is mother to four children, and six-year-old Yeshua, from her relationship with Frank Bonadio, is already showing musical promise.

She tells U.K. Tv host Lorraine Kelly, "They're all very musical. My son Jake is a chef and he lives in London, he's more into the production end of music. My daughter Roisin is almost 17 and she's mad for musicals, she loves musicals. My son Shane, he's only eight-and-a-half and he loves drums.

"But the rocker is Yeshua, the littlest... I think he's the rocker, he's the one who sneaks out of bed and plays my guitars in the night."
