Alec Baldwin deleted his Twitter account following a series of angry tweets directed to a Daily Mail reporter yesterday. He came to pregnant wife Hilaria Thomas's defense due to a story claiming she was tweeting upbeat posts during James Gandolfini's funeral services. Alec later released a statement and said the story was manufactured, while Hilaria shared her hurt over the situation on her own active account.

From Demi Lovato's hot-and-cold feelings about the site to Ashton Kutcher's online silence following a controversial tweet, see celebrities who go back and forth with 140 characters.
