The New York Post is reporting that Alec Baldwin’s brief hospitalization yesterday morning occurred after he had a long-distance argument with his teenage daughter over the phone, which he allegedly ended by saying, “I’m going to take some pills. I’m going to end this.†But then it turned out he’d just taken one Ambien to go to sleep, and then worked a full day filming 30 Rock yesterday. The Post is calling the incident a “suicide threat,†but “a source close†to Baldwin blames his ex-wife Kim Basinger, and speculates that she orchestrated the bad press to coincide with the lead-up to Baldwin’s Oscar-hosting gig on March 7.
