Rihanna Delivers Flawless Vocals At 2015 Grammy Awards

Rihanna brought the vocals to the 2015 Grammy Awards! Praise Jebus! I was genuinely shocked at how effortlessly they flowed from her too- especially after peeping the smoking pre-show picture on Instagram. Even Paul McCartney's mush mouth, confused "singing" wasn't enough to distract me from what I was beholding.

[Watch] Sia Swings From The "Chandelier" with 2015 Grammy Performance

Sia brought a variation of her Chandelier routine to this year's Grammy Awards.Still facing away from the crowd, and with Maddie Ziegler in tow, a change was introduced via the addition of a third dancer, Kristen Wiig...and a shiny new set blonde wigs.

As a majority have probably already seen the original routine for the song, both in its official video format and performed live at various places, it was a smart move from Sia to embellish upon that (very solid) foundation come the Grammys. After all, this is the generation of novelty. So to have not added something new would have had the masses sighing and saying "not this again", instead of focusing on the performance at hand. (Trust me, if Pink can suffer that line of stupidity for her repeated, impressively athletic live renditions of Try, it could happen to Sia.)

[Music Video] Rihanna - "FourFiveSeconds"

Anyone who's seen the promo pic for Rihanna's FourFiveSeconds knew what was coming from its accompanying video.

Christina Aguilera Shows Ariana Grande That Volume Always Win On "We Are The Champions" A Cappella

Who hasn't wanted to hear Christina Aguilera on the same recording as The Roots, Carrie Underwood, Sam Smith, Ariana Grande, Blake Shelton, Usher, Meghan Trainor and One Direction? Well that's just what happened when Jimmy Fallon and The Tonight Show's gathered this unholy ensemble to celebrate the 2015 Super Bowl with a cover of We Are The Champions.

[Watch] Katy Perry Delivers So-So Half-Time Super Bowl Performance

The previous three years of Super Bowl half-time shows must have spoiled me. How else can I explain Katy Perry riding in to her half-time extravaganza atop a giant CAT not making her performance an immediate win for me.

Mariah Carey Performs At The Jazz and Blues Festival, Jamaica

Looks like Mariah Carey can still bring in the crowds, having just performed to a sold-out audience at the Jazz and Blues Festival in Jamaica.

Appearing less polished than usual, the Diva went on to deliver her first live showing of 2015 in a similar fashion. With clearly lipped parts, some more embarrassingly executed than others, Mariah was not on her best form that night. She did look like she was enjoying herself, which is nice to see, but you expect a certain level of professionalism from a veteran like Carey. Her voice did sound better in parts, but the whole performance was in no way near the standard her Vegas residency will require.

Still, sample a taster of what the Elusive Chanteuse brought to Jamaica, below.

[Free For All Friday]

Wow, only four posts between this FFAF and the last one! Oh my, how embarrassing! Still, it has been a fortnight so here it is. In my defense, I do feel like it's been a dry spell for Divas. But you know what they say, it's always quietest before the Storm.
