Christina Applegate is undergoing treatment for breast cancer, but the disease was caught early and the actress is expected to fully recover, her publicist said.

The Emmy winner's cancer was detected through an MRI ordered by a doctor and is not life-threatening, publicist Ame Van Iden said in a statement Saturday.

Applegate is scheduled to appear on a one-hour television special, "Stand Up To Cancer," to be aired on ABC, CBS and NBC on Sept. 5 to raise funds for cancer research.

The 36-year-old actress has been nominated for an Emmy and a Golden Globe for the show "Samantha Who?", in which she plays a woman who wakes from a coma with no memory of who she is.

CUSAK TALKS ABOUT NEW FILM

Known for alternating between mainstream Hollywood and independent films, John Cusack says his latest movie "Shanghai" is a rare middle ground between the two genres.

Speaking at a set visit in Bangkok on Saturday, the 42-year-old star of movies like "Serendipity" and "Being John Malkovich" called "Shanghai" a unique project that combines the artistry of independent film with the resources of a commercial movie.

"To do something that has a big budget, a great scope with a great director and great actors that has the quality and level of writing and the level of production design ... is a once-in-a-lifetime opportunity," Cusack said.

JUST A SMALLTOWN GIRL?

She might be known worldwide as the Material Girl, but there's more than a little of the small-town Michigan girl left in Madonna.

The pop superstar arrived in this northern Michigan resort town Saturday to introduce her documentary, "I Am Because We Are," a highlight of the Traverse City Film Festival. The event was co-founded by filmmaker, author and fellow Michigan native Michael Moore.

Hundreds of fans cheered from behind barricades as Madonna, wearing a black dress, high heels and sunglasses, stepped out of a black sport utility vehicle that pulled up in front of the State Theatre. She hugged a waiting Moore, who sported an orange baseball cap, and posed for photos with him.

LOHAN SNAPS BACK AT POLICE

Lindsay Lohan said Friday that police have no business getting involved in her personal life, a day after the police chief explained that the paparazzi were no longer an issue -- in part because the 22-year-old actress had evidently "gone gay."

"Police chiefs shouldn't get involved in everyone else's business when it comes to their personal life. It's inappropriate," Lohan said in a video shot by paparazzi Friday and posted on TMZ.com. In the footage, Lohan and gal pal Samantha Ronson are trekking through the Los Angeles Airport on their way to catch a flight to Chicago.

The day before, Chief William Bratton said the paparazzi have become less of a problem thanks to Britney Spears, Paris Hilton and Lohan leading more moderate lifestyles.

"If you notice, since Britney started wearing clothes and behaving; Paris is out of town not bothering anybody anymore, thank God, and evidently, Lindsay Lohan has gone gay, we don't seem to have much of an issue," he told KNBC-TV.
