Jessica Biel has joined twitter.

The fiancée of Justin Timberlake created an account on the social networking website and sent out her first post earlier this week.

The 30-year-old 'Total Recall' star - who goes by the handle of @JessicaBiel - shared her debut public message earlier this week while getting ready for an appearance the Met Ball Costume Institute Gala 2012.

Alongside a picture of herself wearing her low-cut Prada frock with assistants attending to the item she sent her first tweet.

The musing read: ''I can't zip up my dress. Welcome to my world!''

Jessica has so far managed to acquire approximately 19,000 followers in two days.

Despite her immediate popularity on the micro-blogging website, she is following three accounts.

One of the people whose news she has subscribed to is her partner Justin.

In a rare display of public togetherness, Jessica and Justin attended Monday's party with the actress proudly displaying her new engagement ring.

The pair, who are reportedly planning to marry this summer, apparently shopped for antique rings and other jewels recently.

An insider told People. ''They definitely seemed fond of each other. They were extremely personable, comfortable and relaxed. They weren't holding hands or anything, but they just seemed comfortable with each other.''
