On 'The Substitute,' we finally get to see the kiddie versions of the Glee cast, and they are just as cute as you'd think they'd be (maybe more). But on Friday, Fox released a new 'Meet the Mini-Me's' video, so fans can gleek out on the pint-sized New Directions crew ahead of time.

This isn't the first time adorable kids have made us go "aww." Justin Bieber used super cute shorty dancers during his four-minute medley at the 2010 Video Music Awards, including his "little bro" Jalen Testerman, who he introduced to Greyson Chance after the show.

 

On Thursday, Daniel Radcliffe, Emma Watson and Rupert Grint wore red poppy pins to the world premiere of Harry Potter and the Deathly Hallows: Part 1 in London, but it wasn't just to look coordinated.

The pins are actually part of a tradition for Rememberance Day, a British holiday like our Veterans Day in which people honor those who have served. The premiere of the highly anticipated film was scheduled on the same day as the holiday, which is why the three stars and other cast members were paying their respects.

 

Justin Bieber hasn't had the best luck on stage. The singer reportedly hurt his knee while performing in Cleveland on Thursday night. TMZ reports that it's sprained, but we're not sure what the extent of his injury is.

"I twisted my knee pretty badly," Justin reportedly said during the concert, but that didn't stop him. The 16-year-old continued performing like a pro.

One year ago (almost to the date), the Canadian pop star broke his foot while opening for Taylor Swift in London. Although he got a lot of love from his fans and the 20-year-old country star -- they even filmed this video about it -- the injury was still pretty major.

Now, we hear poor Justin has a busted knee, and it happened on stage just like when he broke his foot. We're obviously all Beleibers here at JSYK, but we think JB should try to be a little more careful on stage. It seems that he hurts himself every November!

Also, on Wednesday night, the creators of South Park decided to poke fun at the Bieb on their animated series. In the episode, the Dark Lord Cthulu killed Justin so he could get rid of all the "evil" in the world. Eek! Could the show have jinxed the pop star in real life?

 

Thanks Olivia Somerlyn. The soulful 16-year-old from San Francisco has provided us with our current music obsession, her new track, 'Not Your Girl.'

A high school Junior, Olivia is balancing music and homework -- "I'm inspired by the creative process of songwriting, and I'm passionate about telling stories through music, so I'll always make the time," she told JSYK. She writes her own music, plays the guitar and piano and cites some other cool artists as influences.

 

After meeting Greyson Chance a couple weeks ago, we knew we wanted to get to know him better. Luckily, the 13-year-old musical sensation was nice enough to spend Thursday afternoon with us on Twitter, just before he hit the studio where he's working on his debut album.

"I am going to NYC next week to promote my new single Waiting Outside the Lines!" he tweeted to @jsykdotcom during our Twitter-view. "The video for WOTL is coming out very soon."

Greyson also told us that the video will have "a lot of different effects and there is a cool piano I designed for the video. It is more like a mini movie!" Sounds like a Lady Gaga video, right? So then what about those rumors that Greyson and Lady G are collaborating together on his album? "You will just have to wait and see...(:" he teased.

 

Tonight you can catch Britt Robertson and Wizards of Waverly Place's Gregg Sulkin star together in Disney Channel's Avalon High. The movie is based on Meg Cabot's book by the same name, and puts a fun, modern day twist on the story of King Arthur and his Court.

"Gregg's awesome," Britt tells me about her co-star. "We had so much fun...He's a good guy. We became quite close."

They really did! The TV movie was filmed in New Zealand -- which Britt calls a "really gorgeous place" -- and she spills, "We did some crazy stuff."
