Indie pop godess Marina and the Diamonds (aka Marina Lambrini Diamandis) slowed down JB’s “Boyfriend” and made it a little softer than the tender version we’re used to. She performed an acoustic set on Wednesday morning for BBC Radio 1′s “Live Lounge” series along with her new single “Primadonna.” And she KILLED it.

Her cover is a fresh take on the song, which has been playing hourly on the radio, plus she puts a lot of feeling into the vocals. She even went so far as to make a couple lyrical changes, but they work! Her album Electra Heart will be released on April 30th.
