Anne Hathaway took challenging movie roles including her portrayal of Fantine in 'Les Misérables.' On TV, the 32-year-old exuded seriousness too in embodying Miley Cyrus in her quest to beat Emily Blunt on 'Lip Sync Battle.' Was it something Spike asked her to do or she picked it randomly? 

The 'Devil Wears Prada' stars joined LL' Cool J' show battle where the Oscar winner actress chose Miley Cyrus' 'Wrecking Ball' as  her contest piece.  Not contented in following Cyrus' facial expression and singing style, Hathaway packed her performance with similar costume and huge ball hanging antics.    

As showed on Spike's video promo, 'The Dark Knight Rises' gave Blunt a challenging sign. In return, the 32-year-old 'Edge of Tomorrow' star is just laughing in amazement and lip-syncing 'No Diggity.'  The competition of these two actresses will air on April 9.  

Lip Sync Battle is new series inspired from a segment of Jimmy Fallon's, who's one of the program's executive producers, 'Tonight Show.'  In an interview of Yahoo with EP Casey Patterson, the producer shared that they picked celebrities ready for the challenge.

 "What makes this show so much fun to produce and so much fun to watch, in my opinion, is that the celebrities are so committed. They pick something silly and they commit hard to it, and those two were the most competitive we had all season," Patterson said.

"They're best friends, and the competitiveness between the two of them was ridiculous," she said about Hathaway and Blunt duel.  

Meanwhile, Blunt's husband John Krasinski will feature on show's April 16 episode where he performed 'Proud Mary' and battle with Anna Kendrick. In show's   promo video, Anna lip synched 'Booty' and got Jennifer Lopez to back her up in the end.

"We decided that the best possible version of the show is if we don't feed them the songs, that people come up with the songs on their own, because everybody has something that they sing in their car, or a break-up song, or just their jam from high school. The more they know the song and the more emotionally connected they are to the song, the better," Patterson's explanation about their mechanics.
