Sorry, folks, but you will not be getting all the details of Jennifer Love Hewitt's pregnancy and eventual wedding on Twitter. She, like so many stars before her, has decided to step away from the social network, Celebuzz reports. Her account is still active, but she tweeted Wednesday, "Unfortunately with all the negativity people choose to send on twitter as well as threats to there [sic] own well being. I’m sad to say twitter is No longer for me. ... Life should be filled with positivity and holding each other up, not making threats and sending bad vibes." Sadly, she didn't give any details about the "bad vibes" she's received.
