*Oscar nominee Gabourey Sidibe took a trip to the set of “America’s Best Dance Crew” this week where she got to meet one of her childhood crushes – former ‘N Sync member and “Dance Crew” judge JC Chasez. [See photos below.]

Sidibe, a longtime ‘N Sync fan, finally got to hang out with the former singer after months of expressing her love of the group. 

“Wow, what kind of world do I live in now!” she said of the experience.

She also got to witness the dance crews handling this week’s disco challenge, airing tonight at 10 p.m. on MTV. 

Later that day, Sidibe appeared on “Jimmy Kimmel Live.” View that appearance below.
