We can't get enough of Christina's Britney impression!

Christina Aguilera is laughing.

Jimmy Kimmel is laughing.

Hell, we can't stop laughing - and almost 17 million others have already watched the video in just two days.

We wonder, though, if Britney Spears is laughing, too?

Forget the rumbling rumours of silly rifts these days betweeen Katy Perry and Taylor Swift, or Lady Gaga and Madonna.

Back in the day, there was only one showdown in town.

In the 1990s, the biggest rivalry in pop was between bottle blondes Christina Aguilera and Britney Spears.

No wonder Xstina seemed to relish the chance to have some fun at her old enemy's expense on Jimmy Kimmel's famous US Chat show.

In his Wheel of Music segment, Kimmel always gets his guests to do a few musical impressions on the show.

There was only one name most people wanted to see when Christina sat down in front of the Musical Impressions Generator.

It's supposed to be totally random, but we suspect sneaky forces at work.

After already wowing the crowd with her uncanny impression of Cher, Christina cracks up with the next name generated is her old pal Britney.

Even better, rather than something sexy the song selected is famous children's nursery rhyme, This Little Piggy.

"You know Britney Spears, right?", Kimel jokes.

"Little bit," fires back the laughing singer.

The band kicks in with her old rival's most instantly recognisable riff and Christina tries to pull herself together before bringing the house down with her hilarious version of Britney singing the nursery rhyme in the decidedly grown up style of her most famous smash, Hit Me Baby One More Time.

Complete with growls and vocal ticks it is sensational and the crowd goes crazy.

Kimmel himself bows down before the Drrty star.

Later on, Christiana also does a nifty version of the instantly recognisable Shakira yodel, but it's the Britney moment that everyone is talking about.
