It's been 15 years since Britney's second studio album, Oops!… I Did It Again, was released.
And considering her two sons Sean Preston and Jayden James are only nine and eight respectively, they're too young to remember what a massive hit it was: it reached No.1 in 15 countries and to date has sold 24million copies – making it one of the best-selling albums of the decade.
But on Saturday, Ms Spears took her two boys on a trip down memory lane – recreating the iconic album cover at Disneyland, where the trio were spending the fourth of July weekend.
"The boys and I doing our best #Oops album cover pose!" the 33-year-old posted to Instagram along with the relevant snap.
Britney was dressed down for the occasion, wearing grey shorts and a comfortable floral top along with runners.
In an earlier photograph, the singer had wished her fans a "happy 4th of July from the happiest place on earth #Disneyland!!"
Sean and Jayden, along with Ms Spears’s seven-year-old niece Maddie, have all worked her before too: they made music video cameos in Work Bitch and Ooh La La, the latter of which featured on The Smurfs 2 soundtrack.
The star is shortly returning to Las Vegas to continue her run of successful shows there, and is evidently making the most of her down-time.
The Piece Of Me concerts kick-off again on August 5 at Planet Hollywood, and continue into next year. She began her residency in December 2013 and performs 50 shows a year for a €13.6m fee.
Britney is also geared up to release her ninth studio album at some stage in 2015, although the exact date has yet to be announced.
