Sideshow: For Hugh Jackman and Usher, some ouchies

Two of our most beloved wisemen suffered heinous injuries this week at the hands of an uncaring world.

Song 'n' dance man Hugh Jackman, 42, crashed face-first into a studio light rigging Tuesday while trying to impress Empress Oprah during her Australian invasion.

Hugh's rigging had a malfunction when he tried to Errol Flynn his way to an outdoor stage down a cable from the top of the Sydney Opera House.

"That was so much fun, until the end," said the would-be swashbuckler. Thankfully his booboo is minor.

And "U Got It Bad" warbler Usher, 32, got it bad Monday during a show in New York when A Female Fan he brought onstage for his performance of "Trading Places" kicked him in the nose with her stiletto boot-heel.

Seems she was lost in a transcendental transport of ecstasy during the song, which had the couple caress each other on a couch. The R&B man wasn't seriously hurt.
