Her frequent flyer mileage account must be massive, and yesterday Lindsay Lohan was spotted once again getting ready to fly the friendly skies.

The paparazzi caught up to the “Mean Girls” actress as she was dropped off by her girlfriend Samantha Ronson at LAX International Airport, making her way inside to the security checkpoint.

Soon after her arrival in New York City, LiLo found herself in the center of more controversy as she flew off the handle and punched a paparazzo in the face outside the Bowery Hotel.

According to a witness, Lindsay tripped over a metal barricade while chatting on her mobile phone. And apparently she thought the shutterbug had tripped her, because she wound up and socked the guy in the face.

We’re used to seeing her getting cozy with her boyfriend/Heroes co-star Milo Ventimiglia. But yesterday (September 14), Hayden Panettiere was spotted locking lips with a different dude.

But it wasn’t an act of cheating - the Save the Whales Again activist was on the set of her current movie “I Love You Beth Cooper” filming scenes with her co-star Paul Rust.

And Miss Panettiere looked totally hot in a sexy strapless merlot-colored dress as she spent the day on the Los Angeles, California set.

“I Love You Beth Cooper” is about a nerdy valedictorian who proclaims his love for the hottest, most popular girl in school during his graduation speech. It hits theaters March 27th, 2009.

It was a big night in Los Angeles on Sunday (September 14), as Disney partnered with City of Hope to hold a benefit concert featuring Miley Cyrus and the Jonas Brothers.

Also featuring the Jonas Brothers' opening act, Demi Lovato, the Gibson Amphitheatre show helped support cancer research and treatment programs at City of Hope.

“We are honored and grateful for the generosity of Disney, Creative Artists Agency and the dedication of Miley Cyrus and the Jonas Brothers in supporting the lifesaving work of City of Hope,” said Michael A. Friedman, M.D., president and chief executive officer, City of Hope. “This Concert for Hope demonstrates their commitment to improving the lives of patients with cancer and to helping create a future in which cancer is not only treatable, but curable and preventable.”

Last night's star-studded performance continues in a line of charitable giving to the organization from both Disney and Miss Cyrus, as last year, Disney donated $1 from every ticket sold during her highly successful “Best of Both Worlds” concert tour - raising more than $1 million.

Out promoting her latest venture, Selena Gomez attended the premiere of her straight to DVD movie "Another Cinderella Story" at the Grove Pacific Theaters in Los Angeles on Sunday (September 14).

Meeting the press and lots of eager fans, the 16-year-old Disney starlet smilingly posed alongside co-star Andrew Seeley as they promoted the Damon Santostefano directed flick.

Being watched over by a full security team, Selena looked covergirl cute in a grey belted mini dress paired with matching open-toed heels.

As for her new movie, "Another Cinderella Story tells the tale of "A guy (Seeley) who danced with what could be the girl (Gomez) of his dreams at a costume ball, but only has one hint at her identity: the Zune she left behind as she rushed home in order to make her curfew. And with a once-in-a-lifetime opportunity in front of him, he sets out to find his masked beauty."

Enjoying the company of Nashville Star hunk Justin Gatson, Miley Cyrus had an action-packed Saturday (September 13), as she was surrounded by family and friends during a Pasadena outing.

As previously reported by Gossip Girls, Miley spent the afternoon hanging with her gal pal at Coffee Bean. But the most interesting part of the Disney starlet's day came prior to her caffeine stop.

The 15-year-old "Hannah Montana" singer/actress was spotted playfully poking and laughing with a chiseled young male companion, with the duo, along with Miley's family, going to church together before grabbing lunch at the Cheesecake Factory.

And with Cody Linley telling press that he and Miley are just friends, it looks as if Miss Cyrus may be venturing into the dating pool away from her fellow Disney stars!

Not far removed from giving birth to twins, Jennifer Lopez made her way through the Nautica Malibu Triathlon, finishing in three and a half hours on Sunday morning (September 14).

Raising her arms in the air as a victory, J. Lo smiled as she crossed the finish line after swimming, biking and running. "Thank you guys so much. This is an amazing day,” she told event onlookers.

Lopez got her inspiration to race while pregnant, as she told ABC's Good Morning America: "I was beached like a whale. I was watching TV, and I saw a triathlon and I said, 'You know what? I think I could do that, that would be great for me to do. Maybe I'll do it this year.'"

Getting back into shape after having her twins in February wasn’t the only thing that was rewarding to her. "I feel really great and so glad I finished and that I made it out of the water but more amazing than that, I feel really great that we raised $127,000 for the Children's Hospital and hopefully it'll go to good use," Lopez said.

Meanwhile, hubby Marc Anthony cheered on his wife from the sidelines, with the two sharing kisses in between the biking and running sections of the race. When Lopez reached the finish line, she joined him as well as her family and fellow racer Matthew McConaughey in the VIP area. Supporting McConaughey was girlfriend Camila Alves and their child Levi.

“Swimming is a killer," Lopez explained. "I'm not going to lie." The whole event was able to get $950,000. Fans supported her and threw up high fives when they saw Jenny from the block in on the act. She joked around saying, she was going to finish, “even if she has to crawl across the finish line.”
