Robert Pattinson's Fiancee FKA Twigs Sings And Dances To Sia’s ‘Elastic Heart’ On BBC Live Lounge [VIDEOS]

Robert Pattinson's fiancee FKA twigs gave a mesmerizing live performance of Sia's track “Elastic Heart” for BBC's Radio 1. The British singer made the song completely her own as she belted out the lyrics in her unique and melodious voice.

The 27-year-old's voice was mild and haunting as she sang Sia' famous number from her 2014 album, “1000 Forms Of Fear.” Twigs was also accompanied by a male dancer, who moved magically to her melodious voice, creating what can only be described as a captivating performance.

Twigs and her backup dancer were so deeply immersed in their performance that they both looked oblivious to their surroundings. Twigs is also the first singer, who has attempted to add choreography to a BBC Live Lounge studio performance, according to Stereogum.

Apart from covering Sia's “Elastic Heart,” twigs also performed her new song “In Time,” from her latest album “M3LL155X.”

The “Glass and Patron” singer also took to Twitter to share the video of her performance. “We performed in time and ‪@sia's elastic heart on ‪@bbcr1 live lounge this morning -http://yt-r.uk/fkallounge,” she tweeted.

Twigs' rendition of “Elastic Heart” became an immediate hit on social media and received several positive comments.

“I really appreciate when artist [sic] don't try to do an exact copy of the original version of the song. no one can sing a sia song like she does, this is twigs cover and has a complete different approach,” one fan wrote on the YouTube page of her performance.

This is not the first time Twigs has performed for BBC's Live Lounge radio series. She earlier covered Sam Smith's "Stay With Me" on the same radio show over a year ago and won accolades for it.
