Chantelle Houghton has announced she is 11 weeks pregnant with her first child.

The 28-year-old reality TV star had been about to begin IVF treatment with fiance Alex Reid when she discovered she was pregnant.

Chantelle told OK! Magazine: "'Oh my God! I'm pregnant. Let me through - I'm going to be the yummiest mummy there is.

"This really is my miracle baby. I don't know exactly when the baby was conceived. I can't even believe I'm pregnant. I found out four weeks ago - it's been so hard keeping it a secret. I can't wait to go crazy shopping for the baby."

Chantelle had believed her chances of having a baby were ruined by years of extreme dieting and bulimia following her divorce from Ordinary Boys frontman Samuel Preston, who she met on Celebrity Big Brother in 2006.

She has vowed to call her baby an unusual name, joking that Beetlejuice was one of the names she was considering.

Alex, 36, proposed to Chantelle on The Saturday Night Show on Irish state broadcaster RTE One in October. He is still waiting for his divorce from Katie Price to be finalised. They split earlier this year after an 11-month marriage which began shortly after he finished his own stint on Celebrity Big Brother.

Chantelle said: "We are stronger than ever. It's brilliant. We've been together nearly nine months but it just feels so right.

"We don't argue. There are no issues. Me and Alex are just like kids, two peas in a pod."
