We got donations, right here in River City.

Nicole Kidman shocked audience members Saturday night with a surprise visit to Broadway’s “The Music Man” … but a visit to River City was not all she had planned.

The “Moulin Rouge” actress bid $100,000 for Hugh Jackman’s signed hat that he wears in the show’s final number, according to a photo posted on Jackman’s Instagram.

In the post, Kidman can be heard off-camera making the bid, causing the audience to go wild with delight at the actress’s appearance.

The 55-year-old actress is then seen walking down the aisle of The Winter Garden before embracing her “Australia” costar.

“The generosity and love emanating from Nicole leaves me speechless,” Jackman wrote in a post. “Thank you Nic for your friendship and support!”

Kidman responded to the post expressing her love for her dear friend.

“Darling Hugh, To my friend of 30 years Right back at you such a generous gorgeous man,” The “Big Little Lies” star commented.

“It was a brilliant night in the theatre and an honor to be able to donate to @bcefa! Congratulations to the talented cast

The Post reached out to Kidman for comment.

Kidman’s donation will go to Broadway Cares/ Equity Fights AIDS, a nonprofit organization that helps provide medications, health care, nutritious meals, counseling and emergency financial assistance to people across the United States.
