Britney Spears' habit of making the news in 2007 has helped her top the list of the ten most popular searches on internet search engine Yahoo!

The 26-year-old, who is currently embroiled in a custody battle with ex-husband Kevin Federline, has fascinated the world with her erratic behaviour this year, including shaving her head; attacking a paparazzo's car with an umbrella; spending time in rehab; and leaving the industry world gobsmacked after a terrible performance of her last single at a recent award ceremony.

And while she might not be hitting the headlines for the right reasons, Britney's life continues to attract attention, leading to today's announcement that she has topped the Yahoo! search list for the sixth time in seven years.

"People do not know what to expect from her any more and the searches would spike every time she was back in the news," said Vera Chan, senior editor at Yahoo!

"From when she shaved her head and rumours 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."

Britney's former friend Paris Hilton was the only other person to top the list, in 2004, and was the third most popular search term this year, Chan confirmed.

"The tolerance for her party behaviour was fading, but her jail sentence popped her back up to that level of attention," she added.

Lindsay Lohan's arrest for driving under the influence saw her climb from tenth to sixth, while better behaved celebrities Beyonce Knowles and Jessica Alba finished in fifth and tenth respectively.

The top ten most popular Yahoo searches in 2007 were:

1. Britney Spears
2. WWE
3. Paris Hilton
4. Naruto
5. Beyonce Knowles
6. Lindsay Lohan
7. RuneScape
8. Fantasy Football
9. Fergie
10. Jessica Alba
