Brian McFadden secretly married?

Celebrities often take to Twitter to make announcements or set the record straight and it seems as though one pop star may have used the social networking site to reveal a secret.

Rumours are flying that Brian McFadden and his girlfriend Delta Goodrem have tied the knot after he referred to her as his "wife".

As RTE.ie reports, the former Westlife singer tweeted the top five things he did this week, including going to the dentist and buying a turkey for the second time.

However, he described number one on his list as "a secret". This was followed by a post stating: "My sexy wife looks so beautiful lying asleep next to me."

This suggested the pair may have decided to walk down the aisle away from the glare of the media.

McFadden is not the only star to allude to a wedding via Twitter, as last month rapper P Diddy claimed he was set to tie the knot on February 14th 2011.

However, he later admitted this was a joke, adding: "She aint sign the prenup!!!"
