Strictly Come Dancing kicks off this weekend and Andy Murray's mum, Judy, has been practising her first routine.
But, the Wimbledon champion said he doesn't think his mum's chances of winning are too high.
Andy said: "I've never really seen her dance before. But I hope she has a good time, I'm sure she'll enjoy it."
He added: "She's told me she's been having fun with all the training stuff. Hopefully she can do well."
Do your parents look good on the dance floor?
My mum has starred in many west end productions, so she's good, and as for my dad, he's an embarrassment when he dances.

My mum is actually quite good at dancing, she used to be a ballroom dancer. I don't know about my dad, but if his dancing is like his singing... well you don't want to hear that!

My parents CAN'T dance at all! I don't allow them to dance in public because they're so embarrassing. I remember I once let my mum up to do some Greek dancing, never again will I make that mistake!

When my dad dances I nearly die of embarrassment. His shimmies and shakes may be cool in Pluto, but definitely not on Earth.
