In what looks set to trigger a few marital arguments, Beyonce has been deemed a more powerful celebrity than her husband, US rapper Jay-Z.

The singer and actress came in fourth on the 2008 Forbes Celebrity 100 Power List, three places ahead of her husband.

The list was topped for a second straight year by the Talk show host Oprah Winfrey, who has taken the crown a total five times during her career.

US golfer Tiger Woods, who is currently battling a knee injury, was number two on the annual list, which takes into account earnings and press coverage.

Jay-Z was joint seventh in the list alongside The Police, who took their place in the top-10 thanks to earnings from their recent reunion world tour.

In what was a powerful year for film stars, a number of musicians, including Madonna, The Rolling Stones and Sir Elton John, lost their place in the top-10.
