Rihanna joined Coldplay in Paris this weekend (totally typical, right??) and delivered a stripped down version of her hit "Umbrella" accompanied by Chris Martin (a.k.a. Gwyneth's hubby). 

How did she do, Instincters? Find out after the jump.

We've fallen in love with Robyn's "Call Your Girlfriend" all over again this week following the Swedish pop star's SNL performance last weekend, just like we've fallen in love with hot boys alongside acoustic guitars this week, too. The latest to catch our attention is Denmark's Christopher who tackles both our loves for the week in one fell swoop. Follow the jump to watch. 

When in need, you can always count on Kylie! Ms. Minogue released an exclusive video of a backstage jam session, and we've already got it on repeat! Follow the jump to hear Kylie take on a (beautifully) acoustic version of an oldie but goodie!

Mother Monster performed a piano-only version of "Edge Of Glory" for the BBC Radio 1's Big Weekend and revealed that the song was inspired by...her grandfather? Watch after the jump!

Acoustic Kylie, ladies and gentler ladies! Here is her performance from Toulouse, France singing "Nu-Di-Ty":

...and it's good.

What do you think of the acoustic cover from the seminal lesbian band's frontwoman?

We obviously can't get Kylie out of our heads, and the latest video uploaded to her tour blog includes a backstage acoustic performances of "Wow" and "Red Blooded Woman," recorded in the moments before her final show in NYC. What a treat!

Enjoy!
