Kerry Katona could miss her own hen party.

The Atomic Kitten singer - who will marry George Kay next month - has been left in agony with a shoulder injury and is in so much pain, she is concerned she will miss out on celebrating her single days overseas with female friends.

She tweeted on Monday (11.08.14): ''Think I'll be the only hen to have a hen party and not be there the way this pain is carrying on!!!! Rotator cuff! (sic)''.

And Kerry - who has four children from her previous marriages and three-month-old daughter Dylan-Jorge with the former rugby player - felt even worse yesterday (12.08.14) as she was also hit with a migraine, so had an early night in a bid to get rid of the crippling headache.

She tweeted: ''Have had the worse migraine ever today plus this bloody shoulder! In bed getting some sleep got a big day tomorrow xxxxxx (sic)''

Luckily, the sleep seemed to do the trick, though her shoulder is still causing her problems.

She wrote this morning (13.08.14): ''Good morning people, omg I feel sooo much better thank goodness!! Still in pain with my shoulder but my headache has gone!! Have a great day (sic)''
