(Cover) - EN Showbiz - Hugh Jackman's "sweaty undershirt" was sold for a staggering $30,000 earlier this week.

The Australian actor was performing his Hugh Jackman Back on Broadway show on Tuesday night, which was attended by Hollywood stars Scarlett Johansson and Uma Thurman.

Hugh gave a "shout to his friends" during the concert, according to the New York Post.

At the end of the show, Hugh auctioned off his "sweaty undershirt" for charity.

According to the publication, Scarlett ran onstage and bid $3,000 for the actor's piece of clothing, but her offer wasn't impressive enough.

The shirt eventually was sold for $30,000.

Hugh performs with an 18-piece orchestra for the Back on Broadway show and sings his favourite songs.

The hunky star also shares some personal stories with the audience.

Onlookers at the event said Scarlett "looked stunning" even in casual attire. The beauty was dressed down in a "chunky sweater, woolly hat and glasses." (C) Cover Media
