I love how Kellan's the one with the tightest grasp on the choreography, such a darling kid!

This is the cutest thing I've ever seen

I love how his tie reaches his knee! :"> gaaah, so cute!

The tie nearly goes down to his knees, i think that just makes him even more adorable!!!!!

So cute! Is he trying to impress those girls?! ;) PLAYA! His tie awwwwww.

I cant wait will my friends daughter gets a bit older then i am dressing her up like this and teaching her to dance...

I JUST WANT TO HUG HIM TO BAD. HE'S SO DAMN CUTE!!! Great performance :D

This totally made my day. What a cutie. Hope I have a kid who loves glee as much as this little dude

This is the cutest thing I have ever seen! I can't begin to even explain how big the smile on my face is!

He's gonna be a heartbreaker when he's older. He's super adorable right now and he's got the moves! :)

HE'S SO EFFING ADORABLE. I want a Warblette costume! And, when I saw him on the movie commercial, I nearly died. Everything adorable is adorable and shall be adored.

I love how all the girls were looking at him for the moves. xDD

This child is the cutest thing I've ever seen. I sincerely hope he got to meet Darren and some of the Glee cast while he was at ComicCon.

He is definitely already a ladies man! This is so super precious! What a talented little boy!

That kid is soooo adorable!! I love the too long tie on him too. Just adorable!

13 people can't dance like this little boy and are jealous of him... Thumbs Up if u think that Kellen SHOULD BE in Glee!!

Now I'm stalking this kid. When he grows up, he'll be breaking alot of hearts. Swaaaaaag. You're so adorable Kellen.

What an adorable kid! Kellen you are gonna' be a star! And SO cool you met Darren Criss! I'm jealous! ;)

he is my friend

Little dude is such a ham!!!! Just delightful to see people having fun. Fabulous entertainment.

This kid rules! Makes me smile hard every time I see him!

AAH I SAW HIM IN THE MOVIE AND THOUGHT HE WAS THE MOST ABORABLE THING EVERRR~!!!

This kid just brings a smile to my face!!! Thanks girls for the back up support lol

I am the biggest fangirl for this boy. He's too cute.

I can see a little sparkle of myself in those girls eyes. Typical geeks! (Gleeks). This is what I call the epitome of fangirl ness

You're welcome. This was like his 4th time doing Teenage Dream... his energy is AMAZING!

I nearly cried watching him do this. Amazing! :D

Omg he just made my day he is just the cutest little thing ever

he's just too cute! i wonder how they taught him how to dance so well for a kid his age... but never mind that, what matters is the cuteness!

Its soo cute how his tie is too bid for him and its just hanging there! He is adorable!

I love that the warblettes could not stop looking at him so they couldnt get the routinue quite right...while he of course is cool with it..he can do it in his sleep..!!

How adorable is he? SO ADORABLE.

I think Kellen is so amazing. I watched the video a couple of times, and I am just amazed at how well he mocks every move of the Warblers in the screen behind him. Such a talented little guy! I was tearing up watching him, and I don't even know why! This vid was great, and I especially love the other 2 of him with the video playing behind him.. can we expect more of these?? Pinoy pride!!!!!!!!!!!!!!! Keep it up, Kellen! I hope to see you on Glee!

OMG, he is too cute! And he's so into the dance, you can tell he's really enjoying himself! Also, great spin on 0:53 :)

Just saw a preview where darren asked him what he thought of the show and he was like I love it!

He's directing the girls and doing the biggest movements, even though he's the shortest... just like Blaine!

This kid will grow up to be a heartbreaker. He's either gonna grow up to be the next Darren, or he'll look back on this and think "What the hell was I thinking. What were mom and dad thinking?" I hope it's the first :p
