The 'Coronation Street' actress says Kelly - who is good friends with the loved-up pair - has agreed to get ordained so she can play a special part in their upcoming nuptials.

Speaking to the new issue of OK! magazine, Faye said: "We asked her if she would get ordained and marry us, and she said yes!"

Gareth popped the question at the start of the year by getting down on one knee during a trip to New York City, presenting the soap star with a four-carat diamond ring.

Faye - who plays Kate Connor in 'Corrie' - admits it was a "perfect" proposal and she is looking forward to getting married and spending the rest of her life with Gareth, 34.

The 29-year-old actress said: "We were both crying the whole way through. Once it was finished, Gareth got down on one knee and said, 'Will you spend the rest of your life with me?' And of course I said yes straight away.

"It's every girl's dream to find the perfect man for her and then have the perfect engagement, so I feel very lucky.

"To have such a beautiful ring and to share the most brilliant life with my best friend is everything I've ever wanted. He could have but any ring on my finger and I would have said yes."

Gareth and Faye's engagement comes after a brief split last September, but after a few weeks apart they reconciled.
