The singer apparently gave a waiter $100 after he helped calm down her five-year-old son Jayden.
Spears and her brood were dining out eating at a restaurant in San Fernando Valley in Los Angeles with Jayden and six-year-old son Sean when her youngest began crying and wouldn’t stop.
“Britney just couldn’t calm her tyke down,” a source said.
“But a sympathetic waiter, not one assigned to her table, helped save the day when he came over with a box of crayons and started drawing animation action characters. Jayden’s tears dried up instantly as he and his brother got totally absorbed and happy.”
Spears gave the money in addition to the tip for the meal.
Meanwhile, Spears is currently believed to be in negotiations to become a judge on the US version of X Factor, following the departure of Nicole Scherzinger and Paula Abdul from the panel.
The singer will apparently get $15 million to appear alongside Simon Cowell and LA Reid on the TV talent show.
“Both camps were back and forth on the money but now they have finally come to agreement on the fee,” a source told E! News.
“That was the big sticking point and now, thankfully, it’s been sorted. All they need to do now is work out the smaller points. The fact the money is now set, means that there is nothing stopping this from becoming a reality.”
