Your ’90s/early 2000s dreams are coming true: Christina Aguilera can do a great impression of her contemporary, Britney Spears. Aguilera stopped by “The Tonight Show,” where Jimmy Fallon had her do a few musical impressions for him. He did Michael McDonald and David Bowie, but Aguilera turns out to be a pretty good impressionist. While the Britney moment is pretty great, she does a solid Cher and Shakira as well. Remember the days when there was a weird pop rivalry between those two? And then Mandy Moore and Jessica Simpson were in the mix for a while too, before they switched to acting and reality programming, respectively. Ah, memories. Check out the video below.
