According to Yahoo, the 26-year-old mother of two tops their most-searched list because she's unpredictable. "People do not know what to expect from her anymore 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 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."

This is the sixth time in seven years that the pop star has topped the list.
