The pop superstar spent an afternoon serving high tea to her number one supporter James Colbourne at fancy London hotel, The Savoy, as part of ITV's Surprise Surprise Christmas Special.
She was on hand to treat James, his sister Sadie and presenter Marvin Humes to a spot of lunch and even got kitted out in the smart Savoy uniform for the occasion.
And we all know Britney knows how to work a uniform! Who can forget that 'Toxic' flight attendant costume?!
Sadie nominated older brother James for Surprise Surprise to thank him for all of the support he has shown her and her twin boys, George and Riley.
George and Riley were born at just 26 weeks and were diagnosed with cerebral palsy a year later.
But James, 27, has been by his sister's side every step of the way, ensuring that she and the boys have all the help they need, even if it means giving up his own spare time to care for them.
Check out Britney surprising James in the clip and tune into the Surprise Surprise Christmas Special tonight on ITV at 8pm.
