Monica Lewisnky joined Twitter on Monday, posting the hashtag: #HereWeGo under the Twitter handle @MonicaLewinsky.
Almost an hour later, the 41-year-old tweeted that she was “excited (and nervous)” to speak at the Forbes 30 Under 30 Summit in Philadelphia on Monday.
Lewinsky's Twitter bio describes her as a social activist, public speaker, Vanity Fair contributor, and "knitter of things without sleeves."
Vanity Fair retweeted her and welcomed her to the social networking site.
This year, Lewinsky has been making a slow return to the public eye after a decade away from the spotlight.
In May, Lewinsky penned an article for Vanity Fair reflecting on her affair as a White House intern with then President Bill Clinton, saying “it was time to "burn the beret and bury the blue dress."
Lewinsky also talked to "Today" in July about the day details about the affair were revealed by a report from prosecutor Kenneth Starr, saying, “I was the most humiliated woman in the world.”
