Katie Price's son Jett is ''jealous'' of his baby sister Bunny.

The 36-year-old TV star gave birth to her fifth child in August and although she's settled right in to life in the Price household her 13-month-old brother is finding it hard to watch his mum dote on his baby sibling.

Speaking in the latest issue of new! magazine, Katie revealed: ''Having an extra one in the house doesn't really change things. Harvey's taken to her really well. But God, Jett is so jealous of her! If I'm feeding her and I'm standing up, he clings to my legs. He just wants me to hold him.''

Katie - who had Jett and Bunny with her husband Kieran Hayler - took six weeks to pick a name for her baby, but when she did unveil her daughter's moniker she was criticised for choosing such an unconventional name.

But the former glamour babe is not bothered by what other people think about the title Bunny, and she insists it was a popular name in the 1920s.

The busty beauty explained: ''Look, I get stick for everything - don't I? So it didn't bother me. I like the name and that's all that matters. I chose it because I just thought it was cute and different. I couldn't exactly go for a normal name after Princess, could I? It was popular in the 1920s. A lot of people are going back to old-fashioned names. I like Ethel, and Piggy was also in the frame.''

Katie also has nine-year-old son Junior and seven-year-old daughter Princess Tiaamii from her failed marriage to Peter Andre and 12-year-old son Harvey from her relationship with retired soccer player Dwight Yorke.
