Singer Kerry Katona's nagging shoulder pain may keep her away from her own hen party ahead of her nuptials with fiance George Kay.

Katona and Kay are due to marry in September.

A shoulder injury has left her in agonising pain and she is concerned she will miss out on celebrating her single days overseas with female friends, reports contactmusic.com.

"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," Katona tweeted.

The actress has four children from her previous marriages and three-month-old daughter Dylan-Jorge with Kay, a former rugby player.
