Katie Holmes turns every car journey into a dance party - she loves to show off her moves while behind the wheel.
Tom Cruise's wife admits she often lets loose when she's alone and grooving in her car is one of her favorite pastimes.
She says, "In my kitchen, a lot of times, I practise.
"I do dance in my car. In fact... I've gotten caught before. But it doesn't stop me because I think, 'You know what? I like to do it.' And when I see other people do it, I'm like, 'That's right, enjoy it!'"
Leggy Katie Holmes insists she's still a safe driver because "it's all upper body" - but she confesses to occasionally resting her left foot when she's forced to drive smaller vehicles.
Appearing on talk show Late Night with Jimmy Fallon, she explains, "Well, there are certain cars that are tiny and sometimes my leg gets cramped so I do this (puts leg up on the seat) and just use the right (foot)... That's not illegal!"
