GRAMMYS 2013: TAYLOR SWIFT SINGS ALONG TO EVERY SONG — PICS

Those who flock regularly to the Fillmore, the 9:30 Club, or Jones Beach Theater know that the best part of attending live music shows isn't simply watching the performances, it's joining in with them. You can't help but sing along at a concert put on by a beloved artist or group, be you a tone-deaf recluse or an industry superstar in your own right. The Grammys showcased a certain celebrity's proclivity for keeping up with the spotlit performers: Taylor Swift, caught on camera (several times throughout the show) exhibiting her fandom for fellow professional musicians.

When Mumford & Sons took the stage with "Babel," Swift was spotted joining in... 

When Bruno Mars and Sting paid tribute to the late Bob Marley, Swift's enthusiasm became unbridled...

And when the Lumineers kicked off their own ditty towards the end of the ceremony, Swift led the crowd in adoration.

Her own music might be polarizing. But we can universally deem Swift the perfect concert audience member.

Justin Bieber Sings Love Song To Selena Gomez On ‘SNL’

We hope Selena was watching Justin’s ‘SNL’ performance on Feb. 9! Justin clearly dedicated the song ‘Nothing Like Us’ to his beautiful ex. Do you agree?

After apologizing to his fans for smoking weed while hosting the Feb. 9 episode ofSaturday Night Live, Justin Bieber sang a love song, “Nothing Like Us,” to Selena Gomez, which he allegedly wrote about her!

Justin, 18, had many great moments on the Feb. 9 episode of SNL, but it was when he sang “Nothing Like Us,” that he really pulled at our heartstrings.

Singing into a mic hanging from the ceiling, Justin seductively stared into the camera as though he was singing directly to his ex-girlfriend, 20.

We can only imagine what Justin was thinking when he sang, “I gave you everything, baby, everything I had to give. Girl, why would you push me away?”

Justin Bieber Apologizes For Smoking Weed

During one sketch, Justin played the president of Miley Cyrus’ fanclub, making an appearance on the fictitious Miley Cyrus Show!  The conversation quickly turned to Justin’s personal life:

“I also heard he got busted for smoking weed and he’s really sorry about it and people make mistakes and he’s never gonna do it again,” Justin said.

“Yeah, right. Me too,” joked “Miley,” as the audience roared with laughter.

During the later sketches in the show, Justin was impersonated by cast members who posed as his body doubles and he participated in a “Californians” sketch.

What did you think of Justin’s hosting gig, HollywoodLifers? Watch his performance below!
