The future Mrs. Timberlake is now on Twitter!

Jessica Biel joined the microblogging site Monday to start sharing her thoughts with the world. Her first message to her 20,000-plus followers?

"I can't zip up my dress. Welcome to my world! Met Ball," the Total Recall star, 30, wrote, sharing a photo of a stylist helping her into her form-fitting, silver-and-green Prada gown.

Since then, Biel has shared photos of the NYC skyline ("NYC from a chopper. Yeah I said it. Chopper," she tweeted), and showcased a side of herself the public isn't so used to seeing: her appreciation for inappropriate jokes.

Using the hashtag, "#UseTittiesinAMovieTitle," the actress suggested a number of possible breast-focused remakes."Titty Titty Bang Bang. Big Trouble in Little Titties. Punch Drunk Titties," she wrote. "This is fun."
