Christina Aguilera Impersonates Britney Spears, Sia And Lady Gaga In 'The Voice US' Promo (VIDEO)

Christina Aguilera Proves She's The Master Of Impressions
|

Christina Aguilera may be famed for her voice, but she is fast earning herself a reputation as a decent impressionist after taking off the likes of Britney Spears and Lady Gaga in a hilarious new promo for ‘The Voice’.

The singer, who serves as a coach on the US version of the talent show, sent up some of her fellow popstars in this clip, to promote the finale of the eighth series.

While a recent appearance on ‘The Jimmy Fallon Show’ proved that Xtina has already mastered Britney’s singing voice, she's now perfected Brit's speaking voice too, and in the new clip she's dressed up as her former ‘Mickey Mouse Club’ co-star.

Christina also transformed into Miley Cyrus - complete with foam finger and wagging tongue - Lady Gaga, Sia, and fellow ‘Voice’ coach Shakira.

However, our favourite impression has to be Xtina’s hilarious take on Cher, who is a little confused by what the show’s famous spinning chairs are for.

Watch the full clip above and take a closer look at Christina playing dress up below...

Even singing greats can mess up time to time. Christina famously forgot the lyrics to the National Anthem, belting out "Whose broad stripes and bright stars through the perilous fight, what so proudly we watched at the twilight's last reaming." The song's proper lyrics are: "Whose broad stripes and bright stars through the perilous fight, o'er the ramparts we watched, were so gallantly streaming." (credit:Getty)
