As always, NBC's 'The Tonight Show' caters good comedy and harnesses other talents that celebrities aren't really known for. In the most recent episode of the show, it was singer and actress Christina Aguilera's turn on the hot seat that surprised everyone with her talents impersonating other celebrities.

It was a fun sight to see Aguilera loosening up and cracking jokes with the host of the show Jimmy Fallon. Aguilera was invited to play a game with Fallon in impersonating different artists like Cher and Shakira. But when she did her Britney Spears impersonation singing 'Three Little Pigs' in the tune of Spears' 'Oops I Did it again', the audiences were in awe at how well Aguilera imitated Spears.

As Aguilera copied Spears, reports speculate that the two may gain tension once again as they were previously reported to have had a love hate relationship especially that they are two of the biggest hit singers in their time during the '90s.

But apparently, there is no tension as a source from Hollywood Life revealed that Spears was not at all offended by Aguilera's impersonation of her but was even impressed by her. "Britney saw it and thought it was pretty great, they have had their issues in the past but Brit thought is was light-hearted and fun and she never thought it was mean-spirited at all," the insider revealed adding, "Brit is happy she did it so well."

Now Aguilera and Spears' fans can now relax a little bit but there is no official comment yet coming straight from the famous Spears. But Aguilera however was not the only one who had that talent. Apparently, Ed Sheeran, the rising singer for his hit song 'Thinking Out Loud' impersonated Aguilera and did his version of her 'Dirrty' at his visit at the Live Lounge on BBC Radio 1 yesterday.
