Sitting on the sidelines with the other parents, the superstar singer took photos and videos of Jayden while he ran around the football pitch.
Brit looked fab in hot pink shorts and black T-shirt – showing off her bronzed glow from a recent holiday to Hawaii with her kids Preston, nine, and Jayden, eight.
The star was also clutching a copy of a Danielle Steele novel – we love that Brit is just like us!
Britney, 33, recently said she's happier than she's ever been with her thriving career, two healthy sons and a loved up romance with producer Charlie Ebersol.
"I'm the happiest I've ever been," she told People. "My kids come first in my life, bottom line.
"Preston is very opinionated, very expressive, and if he doesn't like something he's going to tell you. But he has a huge heart, he's a good kid and he has manners.
"Jayden is sweet, very soft-spoken, kinda funny. He's adorable – a momma's boy."
It was a very good weekend for Britney as her Las Vegas show Britney: Piece Of Me picked up two awards from readers of the Las Vegas Review-Journal.
The extravaganza at Planet Hollywood – which has been visited by a string of celebrities – was named 'Best Overall Show' and 'Best Bachelorette Party'.
Britney through the years!
