Katie Price plans to name her baby something ''crazy''.

The mother-of-four - who has 10-month-old son Jett with her estranged husband Kieran Hayler, along with Harvey, 12, Junior, eight, and Princess Tiaamii, six, from previous relationships - has yet to decide on a name for her unborn daughter, but intends to choose an unusual moniker so her new arrival has a name like her sister.

She announced on ITV chat show 'Loose Women': ''I'm stuck for names because of Princess. I have to name the baby something probably as crazy as Princess.''

Katie, 36, dumped Kieran after discovering he had been having an affair with her former best pal Jane Pountney for several months, as well as cheating on her with another woman, and says the trauma has resulted in her putting on weight.

She said: ''I don't mind the public. I don't mind anyone else criticising me because nobody's perfect but when it's at home and your other half (it's not good).

''I'm insecure at the moment anyway because I did put on four stone but because my husband cheated on me. Now I carrying completely differently now than I did then.''

The star believes Kieran - who she has hinted she is willing to give a second chance - may even have strayed because of her baby weight.

She added: ''As you know you can't help what your body is going to do. I've been pregnant the whole time I've been with [Kieran]. He only knows me pregnant. It's my own fault. He doesn't actually know me small.''
