Turns out Rihanna's not the Only Girl In The World! (she still is in our heads)
She originally performed the cover in Radio 1's Live Lounge for that there Fearne Cotton.
She's releasing the cover version as a B-side to her new single Lights, and is availble to download from today.
This very day!
What do you think?
We're unsure. As usual.
Only Girl In The World is a great song, GREAT, but it needs to be sung with a bit of kaPOW, don't you think?
Ellie's voice is beautiful, but it's quite floaty and light, so we don't really know if it suits the song.
Hat's off to her for having the man-goolies to cover it though, we just think we prefer the original.
What about you folk?
