Kristin Cavallari is planning an extravagant first Christmas with her new son.

The former 'The Hills' star - who gave birth to her first child Camden in August - is already looking forward to passing on her family's festive traditions with the tot.

The 25-year-old reality TV star - who is engaged to Chicago Bears quarterback Jay Cutler, 29, told US Weekly magazine: ''We always had the elves for seven days the week before Christmas. If you were bad, you'd get coal. If you were good, they'd leave a little something in your stocking, so I want to do that with Camden.

''We'll spend Christmas Eve night at Jay's parents' house and then we will go to my mom's house for Christmas dinner.''

Kristin - who is also a shoe designer - revealed her little boy is already starting to show off his personality and is becoming more active.

She said: ''He is using his hands a lot, so he is grabbing onto rattles and he'll touch your face,'' she explains of her bubbly newborn. ''He's making all kinds of noises.''

But the blonde beauty revealed that she and Jay still have no wedding plans yet despite being engaged since April 2011 and are considering having another baby first.

She said: ''We're talking about it. Things are just up in the air with the baby and deciding if we want another baby first or get married first. Honestly, I already feel like we're married, so I'm not in any rush.''
