Katie Price is pregnant.

The former glamour model - who already has three children from previous relationships - is expecting her fourth child with husband Kieran Hayler.

The couple married just five weeks ago and Katie admitted her pregnancy was a shock, telling the Sun on Sunday: "It comes as a shock. But we're all over the moon.

"I'd be lying if I said I wasn't nervous because I've experienced miscarriages in the past."

Katie, 34, and Kieran, 25, tied the knot after a whirlwind two-month romance but she previously insisted she doesn't care what anyone thinks about their union.

She said: "I know my marriage to Kieran is going to attract criticism and that there will be people selling stories on the back of their perception of me and my decision. I will take that criticism on the chin and argue my corner where I feel it is necessary.

"As usual, I get a hard time for my choices because I'm me - I still don't really understand why.

"This is only my third marriage. I did my own Pricey Marriage Survey and discovered I was in good company. Joan Collins has been married five times, Liz Taylor did eight and Zsa Zsa Gabor nine.

"So there! I get stick, but no one has picked on them for all the marriages they've had."

Katie has children Junior, seven, and Princess Tiaamii, five, with first husband Peter Andre, as well as 10-year-old Harvey from a relationship with Dwight Yorke.

She was also married to cage fighter Alex Reid and split from her last fiance Leandro Penna in October.
