Christina Applegate is wasting no time getting her 21-month-old daughter Sadie into the festive spirit.

Appearing on US talk show Jimmy Kimmel Live!, the Samantha Who? actress spoke about her little girl’s slightly premature fascination with Father Christmas.

“She’s really, really into Santa Claus right now. She’s obsessed,” Christina said.
“We hear her singing 'Jingle Bells' and 'Santa Claus is Coming to Town' in her sleep!”

Alhough it seems Sadie’s new favourite theme is showing no signs of wearing thin, mum-of-one Christina added that she's worried her daughter may have peaked too early.

“I’m nervous that she’s not going to love him by the time we get to Christmas,” Christina admitted.
