Christina Applegate has become a ''dance mom''.

The 42-year-old actress finds herself accidentally criticising her three-year-old daughter Sadie Grace when she watches her perform her ballet routine.

She told ''Sometimes I'll find myself watching her in class, and I'm like, 'Oh my God, you're so being a dance mom. I'm sitting [there] in my head going, 'Why isn't she pointing her foot that way? Someone needs to go in there and fix her foot!' ''

The 'Anchorman' star - who no longer dances herself due to injuries - has always had a passion for the sport and always knew her daughter would take up ballet.

She explained: ''It was my secret thing I did that nobody knew I did. I could go to classes and not have anyone bother me. And I did it for years up until I got pregnant with my daughter. I now have to live vicariously through my daughter. I watch her and help her speak through her body -- channel her emotions and her joy through her body. [I help her] get grounded, get all that stuff out.''

However, the blonde beauty admits she sometimes takes her passion too far.

She added: ''I was stretching her [Sadie's] point today. I was like, 'Let me stretch your point a little bit, Sades. Not for any particular reason -- just giving you a little massage.' I tricked her!''
