Paris Hilton and her boyfriend Doug Reinhardt share their bed with a pig.

The socialite has revealed she and her boyfriend of 10 months often curl up in bed with her new pet - a miniature pig called Princess Pigelette.

She said: "Doug and I will be lying in bed, watching DVDs, and she'll just lie there between us. She's a little sweetheart and I love her."

The 28-year-old blonde star decided to buy the sweet swine after growing jealous of her brother's pig.

She explained to Britain's Hello! magazine: "My little brother bought a little pig when he was in Las Vegas and I was so jealous - I've always wanted one. I went online and found these tiny teacup pigs that stay under 12lb when they're fully grown. They're incredibly smart, lovable, really clean and litter trained."

The 28-year-old hotel heiress - who has a total of 13 pets - is so attached to her animals she thinks of them as her children.

She said: "They're so lovable and the love they give is unconditional. They make me happy and it feels good to have them around. I make sure I take very good care of them all - they're like my children."
