According to E! her official handle is undefined, and to maybe make fun at herself for being a late adopter, her first tweet read: 'I JUST got a super cool new app called Twitter. Twelloooo!!!"
The beautiful blonde, who often stars in comedies, describes herself on her Twitter page as a 'Liver and lover of life; professional laugher, eater, make-believer.'
With 88,332 followers already, Cameron is following 49 celebrities. These include Stella McCartney, Jimmy Fallon, Nicole Richie, Gwyneth Paltrow, Drew Barrymore, Jason Segal, Jessica Alba, Mindy Kaling, Seth Myers, Reese Witherspoon, Kate Upton and Kelly Slater.
British actor James McAvoy tweeted, 'Welcome to the Twitterverse!'
It will be interesting to see whether the busy actress will find time to keep up with her Twitter account but for now, that’s how a star makes a splash!
