Britney Spears was the top search on Yahoo in 2007, confirming what her new song says: Everyone wants a "piece" of her.

Spears, who turned 26 on Sunday, made headlines this year for shaving her head, attacking a photographer's car with an umbrella, going to rehab, fighting with her ex-husband Kevin Federline over the custody of their two sons, releasing her first album in four years and bombing in a "comeback" performance at the MTV Video Music Awards.

"People do not know what to expect from her anymore and the searches would spike every time she was back in the news," Vera Chan, senior editor at Yahoo, told Reuters.

"From when she shaved her head and rumors emerged from the rehab mill that she was calling herself the anti-Christ and shaved 666 on her scalp, there was constant tracking of this almost modern-day Greek tragedy happening in front of us."

Spears has topped the annual Yahoo top 10 list of searches for six of the past seven years, only losing out once — in 2004 — to her pal Paris Hilton. But Chan told Reuters that overall, the Britney Spears searches were up from a year ago.
