'I have butterflies in my belly!Lol wish my mum was here to share it with me!! :-( I'm getting really nervous.'

The combined party comes just weeks after the singer-turned-reality TV star vowed to stand her former rugby player beau after he was briefly detained under the Mental Health Act following a shocking rampage.
He was arrested after 'running in and out of cars' and behaving in a very agitated manner outside the couple's home in Chinor, Oxon.
George - who suffered the equivalent of three minor heart attacks during the ordeal - later admitted that he had mixed steroids, sleeping pills and alcohol before the outburst.

'The brain is so delicate and the doctors said it was a chemical imbalance.
'I had no feeling of madness or that I was going to cause absolute uproar and rampage down the street.
