LOS ANGELES, CA - SEPTEMBER 12:  Actress Emma Stone arrives at the 2010 MTV Video Music Awards at NOKIA Theatre L.A. LIVE on September 12, 2010 in Los Angeles, California.

The 'Easy A' actress follows 'Spider-Man' casting with hosting spot.

It has been a busy year for Emma Stone.

After the unanticipated success of Screen Gems’ little-engine-that-could “Easy A,” Stone snagged the lead role in the adaptation of Kathryn Stockett’s novel, “The Help,” followed shortly by signing on to the “Spider-Man” reboot opposite fall’s other hot commodity, Andrew Garfield (“The Social Network”).

And what’s the No. 1 sign that you’ve really made it? Being invited to host NBC’s “Saturday Night Live.”

“It’s the greatest week of my life,” Stone told THR. “I’m beyond beside myself. This is my biggest dream. This alone … this week!”

The 21-year-old actress — known mostly for her comedic timing — is already in rehearsals for “SNL’s” Oct. 23 episode, with musical guest Kings of Leon.

“Monday was just a pitch meeting, which is really short and it feels like unfinished business, but I’m so insanely happy,” she said. “I think the cast is so great right now, but I’m really excited to [work with] Kristen Wiig, because she’s such a genius, and she’s a woman. I’m freaking out!”

“SNL” was a childhood staple for the Arizona native, who spent her teen years performing in an improv and sketch comedy group.

Nerves aside, Stone is ready for her live performance: “For as long as I can remember this has been my No. 1 dream,” she said. “I’m just trying to enjoy it while it’s happening.”
