Paris Hilton thinks she'll be the ''best mother'' when she has children.

The 37-year-old socialite is currently counting down the days until she ties the knot with her partner Chris Zylka, but she has admitted she can't stop thinking about their future and is desperate to start a family with him because she knows she'll be a great mom.

She told E! News: ''I can't wait to have a baby. I'm gonna be the best mom.''

And the blonde bombshell has plenty of experience when it comes to little ones as she regularly looks after her sister Nicky's children; Lily, two, and Teddy, seven months.

Nicky said recently: ''Whenever she comes over, she comes bearing sweet gifts, clothing, toys, dolls. So Lily gets very excited with Auntie Paris walks in the door.''

Paris - whose parents are Richard and Kathy Hilton - grew up with Nicky and two younger brothers Barron and Conrad so she wants to have ''at least two'' children.

She said: ''I loved growing up in a big family with four kids, with two brothers and a sister. I want at least two ... I definitely want a girl first.''

And she's determined to have a daughter that follows her outrageous fashion choices.

The former reality TV star - who regularly dresses in sequins - added: ''They won't be wearing these kind of outfits but a lot of pink, a lot of hearts, unicorns.''

Meanwhile, Paris and 'Leftovers' star Chris, 32, are set to tie the knot at a no-expense spared ceremony and the businesswoman previously admitted she'd love to don an extravagant dress inspired by the Disney Princesses, who include characters such as Ariel from 'The Little Mermaid' and Belle from 'Beauty and the Beast'.

She said: ''I definitely want it to be very magical. I love Disney princess vibes.''
