Rod Stewart strips off in front of Celtic Board Room trophy case for "no pants" shot

Clearly in good spirits after his performance of Rhythm Of My Heart, Rod decided to shock Twitter with THIS

WOW

It's a sight you never thought you'd see, but believe it or not, it's happened.

Singer Rod Stewart has stripped down to his shirt and no more for a photo in front of the Celtic Board Room trophy case.

We don't know whether to be impressed or disturbed.

He tweeted the snap and added: "I never thought I'd be able to stand in the Celtic Board Room in front of the trophy case... with no pants."

The singer performed at the Commonwealth Games Opening Ceremony tonight - giving a cracking performance of his hit Rhythm Of My Heart.

He tweeted shortly before: "I'm very nervous and very proud to be performing at the Commonwealth Games #2014Ceremony tonight in Glasgow."

  

He was joined on the night by Susan Boyle, John Barrowman, Billy Connelly and Amy Macdonald in Glasgow.

John stole the night with a gay kiss, as Glasgow snubbed homophobic nations in the ceremony.

Within the first few minutes of the opening ceremony, singer John kissed a man waiting at at the aisle for him before the pair skipped away hand in hand.

Viewers were quick to praise organisers for showcasing their support for gay marriage which is illegal in 42 of 53 commonwealth countries.

One wrote on Twitter: "Love that the opening of the Opening Ceremony was a speed date with Scotland with a hosted by a lesbian and a gay man. Gaun yirsel', Glesga!"
