Lady Gaga attends the press conference for 'Gaga: Five Foot Two' during the 2017 Toronto International Film Festival at TIFF Bell Lightbox Sept. 8, 2017, in Toronto, Ontario.

Gaga worked with veterans from Team Rubicon on the project.

Lady Gaga used her downtime before Sunday night's (Dec. 3) show in Houston to lend a hand to some of the victims of Hurricane Harvey. In a series of tweets Gaga -- wearing a white jumpsuit, safety glasses and wielding a crowbar -- teamed up with the veteran-led Team Rubicon to do some demolition on a woman named Pamela's house, which suffered water damage and mold issues due to the devastating hurricane.

"Before the #JoanneWorldtourHouston tonight me and @btwfoundation teamed up with @teamrubicon to do some demolition due to water damage and mold remediation in Pamela's house from Hurricane Harvey," she wrote in a pic with Pamela and her family.

Gaga's Born This Way Foundation also posted a video of Gaga swinging a sledgehammer and breaking out some walls during her volunteer shift before she took the stage later that night at the Toyota Center in Houston.

Recovering - physically, mentally, emotionally- from natural disasters takes time + the work isn’t over yet. Thanks @TeamRubicon for inviting our co-founder @ladygaga to volunteer today in #Houston!

And while the singer got her hands dirty volunteering, that didn't stop her from getting a bit glammed up as well for a bit of Sexy Sunday action.
