The 23 year-old actress plays air guitar to Santana's '1969 hit track.
In the finished film, the 23 year-old actress stars in a hilarious scene where she lip-sync's to 'Live and Let Die' by Paul McCartney & Wings, while giving her house a clean.

Well, the deleted scene is a longer, funnier version which features Lawrence, playing the sarcastic 'Roselyn Rosenfeld,' attempting to lip-sync to Santana's 'Evil Ways' while vacuuming and dancing.
The 4-minute long clip depicts Lawrence throwing her head back and forth, while dramatically tossing her arms around, getting down on all fours and even breaking into an air guitar solo.
The emotionally charged scene was reportedly shot in a single take by director David O.Russell.
Even though Lawrence's performance in the film was one of the year's most memorable, she lost out to Lupita Nyong'o (12 Years A Slave) at the 86th Academy-Awards for the Best Supporting Actress Oscar.

In fact 'American Hustle' surprisingly didn't win any Oscar despite being nominated for 10 awards in several different categories. The night's biggest winners were 'Gravity' with seven awards, and '12 Years A Slave' with three.
However, it wasn't a total disaster for Lawrence at this year's movie award season.
Earlier this year, the 'Hunger Games' actress already won her second Golden Globe, this time for 'Best Supporting Actress', and only a couple of weeks ago, she also picked up the same prize at the BAFTAS's, which usually give good indication of how the Oscars will play out.
