Why is Judy Murray nervous about 'Strictly Come Dancing?'

Judy Murray has revealed that she's nervous about her doing 'Strictly Come Dancing' as her tennis ace son Andy Murray thinks she'll be "absolutely terrible."

The 54-year-old tennis coach, who's been a fan of the show since it began, said that if the champ, 27, comes to see her dance, she's sure he would be embarrassed of her performances and duck under the chairs, the Daily Express reported.

Murray, who's been practicing her moves at home, also said that though she's excited, she's also nervous about dancing in heels and "freezing and forgetting the routine" while live on stage.
