Kate Hudson’s hot head of hair has gotten her into one explosive legal mess.

In June, the “Fool’s Gold” starlet created and launched her own line of hair-care products alongside her longtime celeb stylist David Babaii, entitled David Babaii for WildAid. The eco-friendly collection of shampoos and other styling aids boasts a unique key ingredient, volcanic ash — but perhaps this isn’t so unique after all.

The company 220 Laboratories Inc. filed a lawsuit in Los Angeles Superior Court on Monday against Hudson, Babaii and their manufacturer, Universal, for 17 offenses, including the misappropriation of trade secrets, fraud and breach of contract and confidence.

David Babaii for WildAid defended its product in an e-mail to Pop Tarts:

"We stand by our actions during the research and development process of the David Babaii for WildAid hair care line and believe that 220 Laboratories' allegations are baseless and without any merit. If we are formally served with the complaint, we will vigorously defend this claim," a rep for the company said.

220 Laboratories says it was the only supplier of volcanic ash in the USA and that it entered an “oral contract” with the Tinseltown twosome in August 2006 to develop and manufacture hair products. The company says it revealed their “confidential” ingredient list to Hudson and Babaii in November, and that the duo then took the ash samples and shopped around to find a cheaper deal.

220 Laboratories claims Hudson and Babaii even used promotional footage of the 220 team collecting ash in Vanuatu to promote their products after signing up with Universal.

Kate and her hair-care crew have been labeled “willful and malicious” by the plaintiffs, who are suing for an unspecified amount to include special damages and attorneys' fees as well as an injunction against competitors' use of their products.

Justin Timberlake Says It's 'Painful' to Hear Himself

Justin Timberlake may be a megastar, but the "SexyBack" singer still struggles to accept his artistry.

"It's painful for me to either watch or listen to myself," Timberlake told us recently. "But even when you're not fully satisfied with the outcome, that's what makes you hungry. But there is gratification in the fact that you a. make people smile, b. make people dance, c. make people laugh or d. make people make babies."

Baby-making aside, Timberlake has a very unromantic take on the acting arena.

"Acting is a totally different process than music. Music is a study in the romanticizing of human behavior," he explained. "I have found that acting is like the un-romanticizing, that’s not a word, it is the opposite of the romantics of human behavior."

Perhaps JT just needs a good love scene, as it seems the aspiring actor only chooses gritty roles like a drug-dealing gang member in “Alpha Dog," a disfigured Iraq war veteran in “Southland Tales” and a hairy, Speedo-wearing hockey player in “Love Guru."

Gimme Less: Spears Won't Perform at VMAs

Despite appearing in the promo for the VMAs and weeks of hype surrounding a possible performance, Britney Spears’ manager Larry Rudolph told Ryan Seacrest on KIIS-FM that the pop princess will not be performing at the star-studded awards show on Sept. 7.

Rudolph said that Spears was never signed on to sing and is instead busy working on an upcoming album. But never say never when it comes to Britney — who knows what the girl could come up with that day. ...

Pamela Anderson Doesn't Want You to Watch Her New Show

Pamela Anderson has been busy filming her new reality show “Girl on the Loose,” but it looks like the former “Baywatch” babe was saving face in case not a lot of people tuned in for its debut on Sunday.

"PEOPLE BETTER BE WATCHNG THE OLYMPICS INSTEAD OF MY SHOW!!! You know how E replays things over and over — if people are interested it's always around," she wrote on her blog.

According to Nielsen Media Research, 1.1 million viewers still tuned in to watch, but 1.3 million viewers tuned in right after Pammy to watch the season two premiere of "Sunset Tan" at 10:30 p.m. So we wonder how many times we'll actually be seeing Anderson grace our Sunday night screens. ...
