Actress Christina Applegate's daughter is hooked on all things Santa.

The Anchorman star admits Christmas started months ago for little Sadie, who turns two in January (13).

She explains, "She's really, really into Santa Claus right now... She holds this Santa doll and this reindeer doll all day long. If she doesn't have it she gets really p**sed off.

"I started teaching her about Santa Claus, like, a long time ago and I'm nervous that she's gonna not love him by the time we get to Christmas.

"She loves him so much, you'll hear her on the monitor singing Jingle Bells in her sleep and Santa's Coming to Town (sic)."
