There were no obvious signs of intoxication, but this weekend

Britney Spears

gave herself a whole new image - one closer to

Sinead O'Connor

or

Telly Savalas

.

Esther Tognozzi says that Spears entered her San Fernando Valley hair salon Friday night and demanded the beautician clean-shave her head. When Tognozzi refused, Spears grabbed the buzzers and did the job herself, according to the TV show Extra.

At one point, Spears worried over what her mother might say. Tognozzi said: "I told her it's only hair, it will grow back. I just feel like she thought she had to get rid of all that hair – maybe her extensions were too tight." (Tognozzi later told a reporter that Spears' mom might want to get her child and her grandbabies out of the media circus for a while.)

Spears went a step further that image-changing evening. She then appeared at a tattoo parlor with her shorn head, the Associated Press reported. There, she got a new tat - a pair of red and pink lips.

"She just wanted something real small on her wrist, something dainty," Max Gott, the tattoo artist at Body and Soul in Sherman Oaks, told a TV station. "She got some cute little lips on her wrist."

Derrik Snell, who works at the parlor, said Spears stayed for about 90 minutes as about 60 fans, photographers and gawkers gathered outside.

"She seemed fine," Snell said. "I didn't really notice [the hairdo] at first. She had a hood on when she showed up."

Ghostly Nick

Critics panned Sony's

Ghost Rider,

which was not screened for them in advance, but the

Nicolas Cage

flick led early Presidents' Day weekend box-office estimates, bringing in $44.5 million, according to studio estimates yesterday.

Disney's Bridge to Terabithia, based on the children's novel, came in second with $22.1 million.

The previous weekend's No. 1 flick, DreamWorks' Eddie Murphy comedy Norbit, slipped to third place with $16.8 million. In fourth with $14 million was the Warner Bros. romance Music and Lyrics, starring Hugh Grant and Drew Barrymore. The Lionsgate romance Tyler Perry's Daddy's Little Girls opened in fifth with $12.1 million, a sharp drop from Perry's 2006 Madea's Family Reunion, which premiered at $30 million, and 2005's Diary of a Mad Black Woman, which debuted with $21.9 million.
