Miley Cyrus thrilled her family with a karaoke rendition of her 2010 hit Can't Be Tamed on Christmas Day (25Dec10).
The 18 year old joined sister Noah, 10, for a duet on the youngster's new toy karaoke machine - and she was excited to discover one of her own songs was programmed into the device.
The siblings' big sister Brandi wrote in a post on Twitter.com, "Miley and Noah are currently singing Can't Be Tamed on Noah's new karaoke machine. It's pretty hilarious.
"My Mom is videoing... maybe if you're lucky I'll snag it and upload."
