The former Pussycat Doll is currently filming for this year's series of The X Factor UK, but took time out of her hectic schedule here to fly over to the States to serenade the LA Dodgers baseball fans on Tuesday (30 July).
Singing the national anthem before a Dodgers game is considered a great honour in the US and stars are even encouraged throw to a ceremonial first pitch on the field after their rendition of the 'Star-Spangled Banner'.
Nicole, 35, got into the spirit of the game by donning a Dodgers baseball jersey with a pair of tiny shorts and some fierce black heels. She also looked the business as usual with her brunette hair styled in loose waves and added some sparkly jewellery for a touch of glamour.
She posted a few snaps from the evening on her Instagram account, including one of her singing on the big screen at the stadium and one of her stood with retired basketball legend Magic Johnson.
She captioned the photo: "No matter how hard I tried to stand on the tips of my toes, it's still @magicjohnson! Luv! @dodgers @yankees"
Nicole also admitted what a great time she'd had singing for the Dodgers fans, writing beside another picture: "It was such an honour 2 sing the national anthem @dodgers game 2nite! So much great energy in the crowd!"
The feisty songstress is no doubt keeping herself occupied at the moment after going through a tough break up with her boyfriend of five years, Lewis Hamilton.
Lewis and Nicole split earlier this month, reportedly due to their conflicting work schedules, and both are thought to be devastated.
The Formula One champion even claimed that the break-up had turned his world "upside down" and made sure to let Nicole know that she was still on his mind over the weekend, by dedicating his Hungarian Grand Prix win to her.
