Idina Menzel dedicated her 2014 holiday album to her young son, despite the fact he hates to hear mum sing.

The Frozen star's five-year-old son Walker, whose dad is actor Taye Diggs, inspired Menzel to record her first Christmas album, Holiday Wishes, but he refuses to listen to it because he's not a fan of her voice.

She says, "I have a five-year-old little boy and ever since I had him, it's changed my life and now it's a wonderful celebration and hopefully I can share this with him one day.”

But Menzel admits she’ll have to wait a few years before Walker truly appreciates mum's musical gift, adding, "I’ll do it when he'll actually wants to hear his mother sing. He tells me to shut up."
