Actor’s gesture draws gasps and cheers at charity auction, held after a performance of Jackman’s hit musical The Music Man

Nicole Kidman has surprised both Broadway audiences and Hugh Jackman by bidding US$100,000 (A$150,000, £83,000) for a hat signed by Jackman after a performance of her former co-star’s musical The Music Man.

During an auction for the charity Broadway Cares/Equity Fights Aids after the performance on Saturday, Kidman made her presence known by shouting her bid of $100,000 for the hat, which led to gasps and cheers in the crowd, then a standing ovation.
