Katie Price is eating crushed ice cubes to relieve some of her pregnancy symptoms.

The 35-year-old star is expecting her fourth child this year, her first with husband Kieran Hayler, but the rigours of carrying the tot are taking a toll on her body.

Last night (29.05.13), Katie took to her Twitter page to grumble about her lower back pain and she couldn't stomach eating anything other than frozen water as felt unwell.

She tweeted: ''My lower back is soo bad I cannot walk tonight lying in bed eating crushed ice cubes grrrr (sic)''

Ice cubes have been a regular snack for Katie - who announced she was expecting in February - throughout this pregnancy.

Earlier this month, the brunette beauty complained: ''I have no energy so tired breathless and pale can't stop chomping on ice cubes over half way so not long to go now.''

Katie also has 11-year-old son Harvey, from her relationship with soccer player Dwight Yorke, and son Junior, seven, and daughter Princess Tiaamii, five, with ex-husband Peter Andre.
