There have been many theories to explain the Charlie Sheen train wreck: most centered on drug use or psychological problems. Thursday on 'Good Morning America' (weekdays, 7AM on ABC), one of Sheen's former "goddesses," Bree Olson, said he was just a bored guy who liked to tell jokes and say strange things for stress relief.

What about those interviews in which Sheen claimed to be on a drug called Charlie Sheen? "He would still talk the truth of stuff but at the same time he was just cracking so many jokes because he was just bored," said Olson. "People that don't know him, they just don't get it." Or the podcasts, where Sheen seemed even more out of touch with reality? "Maybe that was his way of venting or getting stress out," said Olson. "Stress relief. Because I was with him almost every time of the day and he seemed perfectly kosher and fine to me."

'Good Morning America' (weekdays, 7AM ET on ABC) reports on Charlie Sheen's very first tweet. Sheen created a Twitter account yesterday and immediately started gaining followers at a staggering rate. Since then, more than 600,000 people have signed up to witness what the troubled star will share.

For his very first tweet, Sheen included a picture of himself and porn star Rachel Oberlin (AKA Bree Olson) with the caption "Winning..! Choose your vice..."

Charlie Sheen's live-in "goddesses" -- former nanny Natalie Kenly and porn star Rachel Oberlin (aka Bree Olson) -- spoke out on life with the 'Two and a Half Men' star on 'Good Morning America' (weekdays, 7AM ET on ABC).

"We all love and care about each other, so we all have our own connections with one another," said Oberlin.

Wendy Williams took a moment to offer gossip on Charlie Sheen's bizarre living arrangement in his Mulholland Estates home in Beverly Hills on 'The Wendy Williams Show' (weekdays, syndicated).

According to Williams, the troubled 'Two and a Half Men' star is currently living with his estranged wife Brooke Mueller, their twin boys, girlfriend Natalie Kenly, porn star Bree Olson and nannies.
