LOS ANGELES (AP) Beyonce danced provocatively in a deep V-neck halter dress at halftime of the NBA All-Star game, two weeks after Janet Jackson's breast-baring Super Bowl performance.

While Beyonce sang her hit ``Crazy in Love'' in the halter dress that gave revealing side views of her breasts, the conservatively dressed Jackson sat courtside swaying to the music.

Jackson's Super Bowl performance created a ruckus that prompted TNT to use a seven-second delay during the All-Star game.

Beyonce descended from the ceiling on a platform above a glittering disco ball singing part of the old Donna Summer hit ``Love to Love You Baby.''

``I'm feeling sexy when I hear you say my name,'' Beyonce sang while dancing in front of six female backup dancers.

She made her way to a platform in the middle of the court and gyrated suggestively in front of a wind machine. Beyonce's vigorous dancing nearly caused her thin, brightly colored halter top to expose her breasts.

Holding a small bouquet of red roses, Jackson sat quietly in her seat during the game. Aside from three burly security guards nearby, she kept a low profile in a furry, brown hat, sunglasses and a brown suede jacket with a white T-shirt underneath.

Accompanied by a drummer, Christina Aguilera performed a backbeat-filled national anthem reminiscent of Marvin Gaye's rendition before the 1983 All-Star game in Los Angeles.

Known for her album ``Stripped'' and penchant for skimpy clothing, Aguilera was downright conservative in jeans and an athletic jacket.
