Lea Michele, best known for her role as preppy superstar Rachel Berry on 'Glee,' is guest-starring on an entirely different show: 'Sons of Anarchy.'

The singer-actress made the official announcement this morning (July 28) via her Twitter:

 

This isn't the first time the Internet buzzed with potential that Lea could appear on the hit television show. Back in March, 'Sons of Anarchy' creator and executive producer Kurt Sutter replied to a PopCrush tweet, hinting that the 'Glee' star might pay a visit to the 'SoA' set. Check out his (sort of) NSFW conversation with executive producer and director Paris Barclay:

Just Jared reports that the episode will be in the series' upcoming final season, although not much else is known about the role. Given Lea's squeaky-clean image both on and off the 'Glee' set, as well as the provocative reputation of 'Sons of Anarchy,' we're willing to bet this will be a huge departure for the actress. We can't wait to find out more!

Lea's had a jam-packed schedule this year. After releasing her first book, 'Brunette Ambition,' the actress announced she'll be penning a followup. We can only hope the book contains more details on when she briefly dated 'Glee' co-star Matthew Morrison, that time she, um, wet herself before singing for President Obama, and -- of course -- details from the set of 'Sons of Anarchy.'
