Singer-songwriter Sia Furler took to her official Twitter page late last night (August 7) to tell her followers that she has just finished working with someone really exciting.

Writing on the social networking site, Sia explained that she has been recording with none other than Jennifer Lopez and she was really impressed by her vocal abilities:

"Worked with jenny from the block yesterday. (@JLo!) what a charming, sweet, funny person. And she can really SING! Anyhoo. Super fun."

She has previously worked with the likes of Flo Rida on 'Wild Ones', which saw her nominated for a GRAMMY Award, and David Guetta on his smash hit 'Titanium'.

Meanwhile, Sia also used Twitter recently to clear up reports that suggested she is dating 'Twilight' heartthrob Robert Pattinson: "As much as I love d**k, I'm not dating Robert Pattinson. Can i go back to being completely irrelevant now?"
