Britney Spears is finally apologizing for attacking a photographer's car with an umbrella in February - but her excuse for the incident is even wackier than her behavior.

"I was preparing a character for a possible movie role where the husband doesn't play his part so they swap places," the singer wrote in a note she hand-delivered to gossip site X17.

"Unfortunately I didn't get the part. I'm sorry I got a little carried away with my role!"

Fresh from her head-shaving and escape from rehab, Spears used a furled umbrella to batter a paparazzo's SUV outside ex-husband Kevin Federline's house during her very public meltdown.

Paris isn't the only one hanging 10 in the Aloha State.

While buddies Ben Affleck and Matt Damon enjoyed a joint family vacation there, sources say they used the down time to rekindle their writing partnership.

"Ben and Matt keep taking breaks to go surfing and hang out with their families," an insider tells Us Weekly. "But for the most part, they've been writing together on this trip."

It was in 1998 that the pair walked home with Oscars for their "Good Will Hunting" screenplay.

Damon's rep confirmed that the duo are set to return to screenwriting.

"That's their plan," she told us. "Whether or not they are doing it right now, I don't know."

BEYONCÉ is taking a page from Britney Spears' book, and it didn't impress the elite Sunday afternoon crowd at Bergdorf Goodman. Last weekend, spies spotted Jay-Z's bootylicious girlfriend browsing for jeans - barefoot. "She was shopping for shorts with two guys," said the onlooker. "I don't know why she didn't have shoes on. She wasn't shopping for shoes." One celeb who did keep her footwear on at the store was "Knocked Up" star Katherine Heigl, who was there at the same time as Beyoncé and "looking gorgeous."

Britney Spears has put her fury with her mother into verse.

The "Toxic" singer has been angry with Lynne Spears because she felt her mother pushed her into rehab. Now, Spears has written a bitter poem entitled “Dear Mama” and delivered it to her mother, according to the Star.

In the poem, Spears lamented “that she didn’t have a mom anymore and she couldn’t imagine a mother doing what she did to her child,” a source told the tab.

Spears delivered the verse, along with legal papers, to her mother on June 28 on the set of kid sister, Jamie Lynn’s television show, “Zoey 101.” The two are reportedly also battling over the affections of Jamie Lynn.

“Britney said, ‘Here Momma, I just wanted to see your face,’” a source told Star. “Then she got into her car and drove off. Lynne went into the trailer and broke down in tears.”

The CD reportedly contained recordings of phone conversations between Lynne Spears and Britney's estranged husband, Kevin Federline, in which the two are apparently working in cahoots.

Spears is forbidding her mother from seeing her two sons, and in one conversation, Lynne is said to be arranging to meet K-Fed and the boys, and says, “I have to be careful that Britney doesn’t find out!” The recordings were made by a private investigator, according to the tab.

In another call, Federline assured Spears’ mother that his court battle with the singer was going well.

“Kevin told Lynne that he had everything under control,” adds the source. “He was just going to let Britney hang herself in court.”

Lindsay Lohan celebrated her 21st birthday sober — but that doesn’t mean she was unhappy.

The rehabbing star was spotted making out with Evan Ross, the 18-year-old son of Supremes singer Diana, according to former publicist Jonathan Jaxson.

“Even more interesting is that she let Samantha Ronson back into her life,” notes Jaxson.

Lohan has had a gossiped-about friendship with the D.J. But, Jaxson comments, “I think Lilo thrives on the drama and loves keeping a regular playboy and girl on hand at all times.”
