London, May 30 : Wayne Rooney's fiancee Coleen McLoughlin has been working out to make sure that she looks her best for the couple's big day. However, she was in for quite a shock after she found out that all that exercising has meant that she no longer fits into her wedding dress as it's just too loose.

Coleen has lost so much weight due to exercising and stress that her 100,000 pounds Marchesa wedding gown has started falling off her, a pal revealed.

"Coleen was so panic- stricken when she tried the dress on as she had not realised how much weight she had lost," The Sun quoted the friend, as saying.

And that's why she made an emergency dash to her New York designers.

"The dress is the most important thing - you cannot blame her for travelling all that way to have it altered," the pal revealed.

The designers Georgina Chapman and Keren Craig will now have to take in the gown, which has a 25ft train, until it fits.

Coleen and Rooney are getting set to tie the knot in a butterfly-themed wedding in Italy.
