According to the Associated Press, Paula Abdul blamed her recent bizarre behavior during a series of satellite interviews on sleep deprivation combined with technical problems. What do you think?:

Abdul told reporters she woke up that day at 3:45 a.m. after going to sleep just before midnight. Technical foul-ups meant she heard questions from one station on an "electronic press tour" but her answers were directed to a different one, she said.

The interviews in question were the last two of 30 she did back to back, she said.

"That's very disorienting in itself because you can't see who you are talking to," she said, according to a blog by Robin Leach on AOL. "It wound up that San Francisco kept asking questions because they couldn't hear me but my answers were actually coming out in Seattle."

"Fatigue and exhaustion just added to the whole thing looking so disoriented," she said. "I just can't explain it, but for me, no excuses and no apologies."
