Kate Hudson Masters “The Star Spangled Banner” on Fourth of July: See How Other Stars Are Celebrating

Forget her "Tiny Dancer" routine — Kate Hudson can really sing! The Deepwater Horizon star didn't care who was listening when she belted out "The Star Spangled Banner" to celebrate the holiday on Saturday, July 4.

"7:30am and I'm feeling seriously patriotic! Happy 4th of July!" Hudson, 36, captioned an Instagram video. "#ProudAmerican #StarSpangledBanner #RedWhiteAndBlue #GearingUpForFootballSeason."

She added: "#MyKidsAreGoingToBeSoEmbarrassed #WokeUpTheNeighbors."

Still wearing her pajamas, the Almost Famous actress wore red sunglasses indoors and held a cup of coffee during her funny performance.

Caitlyn Jenner, meanwhile, shared a very meaningful message. "Happy 4th of July! Proud to be an American…where at least I am free to be me," she wrote.

Other stars celebrating the Fourth of July include Diane Kruger, Jessica Alba, Nick Jonas, and more. Former Secretary of State Condoleezza Rice even posted a video of her playing piano to "Amazing Grace." See more below:
