She was attempting to make the most of the blazing sunshine by enjoying a day out with her husband and son.

But still Katie Price couldn't muster up a smile as she and Alex Reid took her son Harvey to the launch of a new family attraction in Kent.

Wearing a loose white cardigan over a vest top and leggings, Katie, 32, looked subdued and withdrawn as she arrived at the Lost Island Encounter at World of Golf in Sidcup.

Alex, who wore a Star Wars t-shirt with jeans, boots and a leather jacket, didn't look much happier either - but cheered up when he was given a balloon lightsaber to play with.

The couple took Harvey for a stroll around the golf course, which is based around a Lost Island theme and includes cascading waterfalls, 1950s jeeps and a crashed jet plane.

Their subdued behaviour could be down to the fact they have been having trouble conceiving.

According to the News of the World, Katie is furious after finding out Alex had been keeping his fertility problems a secret from her.

A source told the paper: 'They've been trying for weeks and weeks, and she's reached the end of her tether.

'She blames Alex and finds it embarrassing because she told the world she'd have his baby as soon as she could.'

And Alex is said to be finding it difficult to cope with Katie's constant pressure on him to give her what she wants more than anything - another baby.

The source added: 'Katie feels cheated he didn't tell her so she is being vile to him. He feels her obsession with having a baby is destroying their marriage.'
