It was producer Steven Spielberg who demanded that Megan Fox be fired from the latest Transformers movie, says The Daily Mail.

Rumor was that Fox, 25, was fired after comparing director Michael Bay to Adolf Hitler in a 2009 interview. She appeared in the first two films, but has now been replaced by Rosie Huntington-Whiteley for Transformers: Dark of The Moon, which opens June 29.

But The Daily Mail reports that, according to Bay, it wasn't him, but Spielberg, that demanded she be let go. He says: "You know, the Hitler thing. Steven (Spielberg) said, 'Fire her right now.'" Spielberg is Jewish.

At the time, Fox said she left the series to pursue other acting opportunities. Since, she has appeared in flops Jennifer's Body and Jonah Hex.

After Fox made the Hitler comments, crew members from the series released an open, anonymous letter blasting her. Read what they said after the jump.

After vacationing with wife Demi Moore at the Samburu National Reserve near Kenya, Ashton Kutcher is ready to get to work on Two And A Half Men.

The sexy actor, with coffee in one hand and his laptop in the other, arrived at the CBS lot ... and seemed focused on his big TV comeback.

Actress Denise Richards, who was married to the show's former star Charlie Sheen, had the following to say about Mr. Kutcher joining the cast.

"I think Ashton is going to be great. Nobody can replace Charlie. The show was written for him and he was so brilliant at it, but I think the creators of the show are very brilliant and the show is very well written so I think Ashton will make it his own."

Wow. This was quite the story to wake up to Monday morning.

Doug Hutchison, an actor best known for his roles in 1999's The Green Mile and Lost, has revealed that he married aspiring singer Courtney Alexis Stodden on May 20 in Las Vegas.

Vegas weddings are crazy enough on their own, but this one is particularly special. Why? He's 51 years old. She's 16.

"We're aware that our vast age difference is extremely controversial," the couple told E! News. "But we're very much in love and want to get the message out there that true love can be ageless."

Again: Wow.

You can see Courtney above in a photo from her website, where she calls herself "your all American girl." So, if this "girl" is 16, not only is the marriage unsettling ... but isn't it also illegal? Maybe she got her parents' permission ...

Courtney's got some pretty stellar music vids up on her website ... check one of them out after the jump. Handheld video camera = insane production value. Ish.

Glee creator Ryan Murphy confirmed Friday that the current cast of high schoolers on Glee will graduate, from McKinley High and from the show, in May 2012.

Murphy told Ryan Seacrest on Friday that the characters who were juniors last season -- including Rachel (Lea Michele), Finn (Cory Monteith), Quinn (Dianna Agron) and Puck (Mark Salling) -- will graduate in May 2012 and leave the show at the end of its third season. Said Murphy:

"... we didn't want to have a show where they were in high school for eight years. We really wanted it to be true to that experience."

Murphy said Matthew Morrison and Jane Lynch will remain on the show, as their characters Will Schuester and Sue Sylvester are the cornerstones of the series. Murphy says casting calls have already gone out for new glee clubbers, including an "Adele-meets-Susan-Boyle" type.

"I think that just like with the original cast, I think finding those young unknown people and giving them an opportunity to break into the business and become stars is a really fun and exciting thing ..."

Season three of the show premieres in September on Fox.
