NEW YORK – Lady Gaga was in the Christmas spirit at Z100’s annual Jingle Ball concert, but her version of “White Christmas” would have made Bing Crosby blush.

Gaga performed a slightly naughty rendition of the holiday classic Friday night as part of her mini-concert at the radio station’s event at Madison Square Garden. Gaga — sporting tight studded leather pants, matching top and a bare midriff — gyrated on a set that included antlers, Christmas trees and holiday lights as she performed “White Christmas.”

“So I recently added a couple of lyrics to this song because I think it’s too short. It’s like when you really start to enjoy it, it stops. Merry Christmas New York!” she shouted. Later, she made a suggestive pose as she gave a come hither coo to Santa.

But her performance wasn’t all saucy.

She was nostalgic and appreciative as she thanked the radio station for allowing her to be the headliner of this year’s show, which included performances by Kelly Clarkson, Demi Lovato, LMFAO, Pitbull, David Guetta, Foster the People, Hot Chelle Rae and more.

Gaga said her first concert as a young girl growing up in New York City was the Z100 Jingle Ball.

“I worked so hard and when I was 11 my mom got me tickets to the Jingle Ball,” she said.

Gaga opened the concert three years ago. She said, “I’ll never forget — there were a whole lot of superstars and no one knew who the hell I was. Some people thought I was going to be a one-hit wonder.”

The singer, recently nominated for three Grammys, proved to be otherwise, and sang a few of her best-known songs, including “Telephone,” “Just Dance” and “Edge of Glory.”

A portion of the evening’s proceeds will go to “STOMP Out Bullying,” a program designed to reduce and prevent bullying, a cause close to Gaga’s heart.

Last week, she went to the White House to meet with officials about the matter.

“It’s important to keep everybody safe in school,” Gaga told the audience before launching into her inspirational anthem, “Born This Way.”

The concert will air Dec. 18 on the Fuse network.

Actor gets hooked on directing

HAVANA – Puerto Rican actor Benicio del Toro said the labor of love that went into his directorial debut in the movie “Seven Days in Havana” was so gratifying he plans to keep working behind the camera.

“To see the motivation of all the artists, working 14 hours a day, to see the confidence they had in me, the collaboration between everything, is something very special,” del Toro said Friday in Havana, where “Seven Days” is being screened at the city’s film festival.

“It’s an experience that motivates me to dream of trying it again,” said del Toro, who won the 2003 Oscar for best supporting actor for his role as a Tijuana drug cop in “Traffic.”

“Seven Days” is made up of seven shorts, based on stories by Cuban writer Leonardo Padura, that take place on different days of the week and show different visions of Cuban society.

Del Toro directed the first segment: “The Yuma.”

Man ordered to stay away from Dunst

LOS ANGELES – A judge on Friday granted Kirsten Dunst a temporary restraining order against a French man who has written more than 50 letters to her and traveled to Los Angeles at least five times to try to meet her.

Jean Christophe Prudhon of Dijon, France, was ordered to stay 100 yards away from the actress and to stop trying to contact her.

In letters accompanying Dunst’s petition, Prudhon wrote that he sold his home in France so he could to travel to meet Dunst, who has not responded to any of his letters. He wrote that he is in love with her and has repeatedly waited outside her home. Inez Dunst, the actress’s mother, wrote in a sworn declaration that Prudhon came to her door recently trying to meet Dunst.
