Christian Bale has been “missing in action” on the set of his new movie.

He’s filming “The Fighter” in Massachusetts with Mark Wahlberg and Amy Adams and the method actor insists on “getting into character” by refusing to be seen on set.

“You only see him when it’s time for his scenes. Other than that, no one has any idea where he is. He just goes missing,” a source told E!.

Bale is determined to accurately portray former crack addict Dicky Eklund in the movie, which follows the life of boxer “Irish” Mickey Ward.

The source explained: “Christian has lost almost as much weight as he did for ‘The Machinist’. He is so gaunt. They have even thinned his hair, he just looks sickly.”

When filming “The Machinist,” Bale lived on just a can of tuna and an apple a day and lost 60 lbs. to play a paranoid insomniac.

Bale has said he didn’t plan to go to those extremes again, but admits he thrived on the “mental challenges” it presented.

“I wouldn’t want to take it to that extreme again. But it was necessary to lose weight for that role – not as much as I did – but it was a challenge mentally to see if I was capable of doing such a thing.

“I know that I can now, so there would need to be a certain gimmick if I was to do that all over again. But I do like the notion of seeing how far you can push yourself so I’m very happy that I did that. Everybody told me that I was risking my health the first time around, so doing it twice? I’m probably being an idiot.”

Eric Dane and wife Rebecca Gayhearts little naked romp with a teen beauty queen has caught the eye of Los Angeles authorities. They are reviewing the tape, looking for any “criminal activity” as part of an official investigation.

Video of the couple frolicking nude with former Miss Teen USA Kari Ann Peniche hit the internet on Monday.

In the clip, the seemingly drunk trio lounge on a bed, passing a camera around and dreaming up porn names for each other.

An anonymous source gave the Los Angeles Police Department a copy of Dane’s tape last month.

A statement released by the LAPD said, “On July 30, 2009, an unnamed source provided the LAPD’s Detective Support and Vice Division with a copy of a DVD. According to the source, the DVD contained images that could link celebrities engaging in illegal activity.

“The LAPD was in the process of reviewing the voluminous files contained on the DVD when the story was leaked to the media. No determination has been made as to whether or not the DVD contained any information that could be used for a criminal investigation. Some of the information contained on the DVD included archived articles and photographs of porn stars and formally convicted madams, which could readily be found over the internet.

“The LAPD will continue to review the DVD for potential evidence. Therefore, additional information about the contents of the DVD will be treated as confidential.”

Meanwhile, a lawyer for the Grey’s Anatomy actor has threatened to sue anyone who publishes the “private, confidential tape,” adding, “from what I’ve seen, it’s a naked tape, not a sex tape.”

Mila Kunis is calling her boyfriend Macaulay Culkin her “steady rock”.

Kunis has been dating the “Home Alone” actor since 2002 but the two are rarely seen out together and often refuse to discuss their romance with the media.

But Kunis said Culkin plays a huge role in her life because they’ve grown up together, surviving several difficult periods and the trappings of Hollywood at one another’s side.

“I don’t know if I met him at 27 if it would have been a different relationship. We grew up together. You find a steady rock in your life and that’s all you need. We have our ups and downs, but work through them,” she told Women’s Health magazine.

Poor Samantha Burke. Not only is she not an expensive lay, she’s also forgettable for the weeks thereafter. According to sources, Jude Law doesn’t even remember the mother-to-be of his fourth child.

A friend of Burke, who is pregnant with the star’s baby following a brief romance last year, claims the model hasn’t seen or been in personal contact with the Law since he left New York.

“She met him at a club in New York. He was sick, so she kept going to his hotel over the course of a week to take care of him,” the friend told E! Online.

“But Jude didn’t even remember her. She hasn’t seen him since New York. They’ve only been in contact through their lawyers.”

The friend also said she believes Burke “crazy” to go through with the pregnancy.

Burke denied she’s a golddigger on her blog earlier this month.

“I can’t tell you how far from a gold digger I am. I’ve never dated a rich man in my life. I’ve always wondered how girl friends of mine could even ask their boyfriends to buy them clothes.

“When I found out I was pregnant, I was scared. I didn’t jump for joy because I ‘hit the jackpot’- I cried.”

Burke is reportedly requested a little less than $10,000 per month for their daughter, Sophia, who is due in October.
