Katie Price has hinted she could be having twins - who she plans to call Tinkerbell and Lorenzo.

The 35-year-old star - who already has three children, 11-year-old son Harvey, from her relationship with soccer player Dwight Yorke, and son Junior, eight, and daughter Princess Tiaamii, six, with Peter Andre - is currently expecting her first child with husband Kieran Hayler.

Although she has been secretive about her ''humongous'' baby bump, even managing to avoid being pictured in recent months while pregnant, she has revealed she and Kieran have picked out two names.

Speaking at the launch of her new fragrance Kissable in London today (04.07.13), she told BANG Showbiz: ''For a boy and girl we've got Tinkerbell and Lorenzo.''

While her due date is still unknown Katie - who dressed as a giant pair of lips for the perfume launch - appears to be in the final stages of pregnancy and is expecting to give birth ''soon.''

Katie is suffering from lower back pains and is ''struggling'' with this pregnancy and has had ''more health problems with this one''.

Again hinting she could be having twins, she added: ''There's a reason why it's so big ... I'm heavier and struggling.''
