I was crazy for JC when I was a teenager, but now that I am a full grown women, I appreciate him on a whole new level. 13 years and I am still twitterpated.

[ljubi83od2000do2004]

@CharmedPrue77 so true

[moosiekk417]

JC Should Get a Twitter i would totally follow him if he did

[thefloacist]

[obsessed4jc]

Thank u for sharing this with us! I love that Matt has welcomed JC with opening arms throughout a couple dates on his tour. :)

[melissaratliff]

I vote for Matt Morrison to replace Justin Timberlake in NSYNC.

[thefloacist]

@melissaratliff God no. He can't sing or dance. This ain't Destiny's Child, no replacements will be accepted.

[BiLlAbBoNg]

@thefloacist LOL! Matt Morrison can't sing? Yea that's why he spent 10 years on Broadway! It all makes sense now! To be on Broadway, you must be not be able to sing?

[ILOVEJTNJC]

Amazing! See this proves that Nsync can so get back together for a comeback tour if they wanted to. *sigh* I wait for the day that I see that happen. Matt is so gret for doing this for JC <3
