Christina, 34, was asked to do an impression of 33-year-old Britney, while appearing on The Tonight Show with Jimmy Falon, and she didn’t fail to deliver.
The mum-of-one gave a rendition of This Little Piggy in the style of Brit and to the tune of Hit Me Baby One More Time and she nailed it.
Both Christina and Jimmy laughed when Britney’s name came up on the generator. He even jokingly asked if Xtina knew Brit.
“Um, a little bit,” she replied, before delivering the amazing impression.
Britney and Christina both rose to fame in the late 90s, after working on the Disney Mickey Mouse Club.
They reportedly clashed when Christina and Britney’s ex boyfriend Justin Timberlake embarked on a tour together.
The story goes that Britney caught Xtina and Justin kissing in a nightclub VIP area one night, sparking the infamous feud.
It became clear that the two former friends still hadn’t patched things up when Britney became a judge on The X Factor USA – becoming direct competition for The Voice USA judge Christina.
When asked if she’d gone to Christina for advice on being a judge, Britney simply responded: “No, I haven’t.”
