Taylor SwiftTaylor Swift might want to have an ambulance standing by for her upcoming gig as host of 'Saturday Night Live' this coming Saturday. "Starting the SNL process," Taylor tweeted on Monday. "I kinda feel like I might have a heart attack or pass out in the pitch meeting. I'm that excited."

The teenager has already had plenty of jaw-dropping moments. Recently setting a new record for longest charting album of the century, she's also appearing in the upcoming film, 'Valentine's Day,' along with an all-star cast including Bradley Cooper and Julia Roberts, and rumored to be dating 'Twilight' heartthrob Taylor Lautner. In addition, she's up for four CMA awards, including the coveted Entertainer of the Year, and six American Music Awards.

But none of that is on her mind right now, as the 'SNL' date looms closer. "I'm so excited, not sure if I'm ready," she says. "I try to prepare for everything beyond the extent of preparation. So I have all these ideas for skits, I have like 10 ideas right now, I'm probably gonna walk in there with 35 ideas."

Taylor joins a long list of artists who will perform double-duty as host and musical guest on the show, including Dolly Parton, Justin Timberlake and Ludacris.
