London, Apr 25 : Hugh Jackman once missed a rare chance to meet former British Prime Minister Tony Blair, because he was too busy throwing up behind the stage.

The ex-PM made a special trip to see a show of the 1998 London production of musical `Oklahoma!' at the National Theatre, starring the `Australia' star.

But the actor had been struck down with a migraine and was running off the stage to vomit through the entire performance.

The illness kept the actor confined to the bathroom even when the ex-Labour party chief came to meet the crew after the show.

"I remember having a migraine when Tony Blair came to see `Oklahoma!'" The Daily Express quoted Jackman as telling Britain''s FHM magazine.

"I was going into the wings and throwing up whenever I was off stage, and afterwards Tony Blair came backstage to meet the cast, and of course I was throwing up." (ANI)
