Wiz Khalifa, Joan Rivers diss Taylor Swift's 2014 Grammy performance [WATCH]: emotional 'All Too Well' put Amber Rose's hubby to sleep, 'Fashion Police' agree

During the 2014 Grammys, Taylor Swift performed an emotional rendition of her hit song "All Too Well." Apparently, some celebs found the act rather boring...

Following the 56th annual Grammy Awards, Amber Rose and her rapper hubby appeared on an episode of E!'s popular show "Fashion Police." When asked about Swift's powerfully stripped-down performance, Wiz Khalifa responds, "I love Taylor, but I'm not even gonna lie - I fell asleep just a little bit."

Ouch.

Of course host Joan Rivers chimed in with, "I like your watch, how many times did you check it during Taylor Swift's endless ballad?"

But even the "Fashion Police" critics couldn't deny the fact that the 24-year-old "Red" songstress' Red Carpet look was still absolutely stunning:

And Rivers - being the infamously outspoken comedian that she is - even managed to bash Khalifa (but in the funniest way possible):

"I'd like to call Katy Perry's Grammys hair the Wiz Khalifa... Because it's very black and high."

Ha, get it.

Did Mstars fans find Swift's performance yawn-worthy?
