Paris Hilton's In More Trouble

(CBS/AP)  Hours after her release for allegedly driving under the influence, Paris Hilton defended herself to radio host Ryan Seacrest during his Thursday morning show on local station KIIS-FM.

"It was nothing," said Hilton, 25.

The singer, actress, handbag designer and heiress to the Hilton hotel-chain fortune said she was "starving because I had not ate all day" and possibly "speeding a little bit" in her Mercedes on her way to grab a bite.

"I was just really hungry and I wanted to have an In-N-Out burger," said the one-time pitchwoman for Carl's Jr.

Hilton was arrested early Thursday for investigation of driving under the influence, police said.

Hilton's spokesman, Elliot Mintz tells The ShowBuzz that Hilton had one margarita at a charity event before being pulled over by authorities.

The heiress was arrested shortly before 12:30 a.m. in Hollywood, said police officer I. Isabella, who declined to give his first name.

"The officers observed that Hilton exhibited the symptoms of intoxication. A field sobriety test was conducted at scene, and the officers determined she was driving under the influence," said Isabella, reading a police statement.

An LAPD spokeswoman said Hilton was driving erratically.

"Officers observed the vehicle driving in an erratic manner, so they pulled the car over," officer Marjan Mobasser said Thursday.

Officer Isabella said Hilton was booked on suspicion of misdemeanor driving under the influence.

During the arrest she was briefly handcuffed. Hilton was booked at LAPD's Hollywood station at 1:43 a.m. and released shortly afterward, said Nick Velasquez, a spokesman for the city attorney's office.

Mintz confirmed the arrest and said police detected the minimum blood-alcohol level to warrant an arrest. The legal limit in California is 0.08 percent.

In a phone interview with The ShowBuzz,Mintz said Hilton began her day around 5 a.m., and was in Pasadena shooting a music video for her new album and hadn't found time to eat all day.
