Justin Timberlake obtained a restraining order against a photographer who allegedly was stalking the pop star.

"It's about time that somebody did something about these stalkerazzis," said Timberlake publicist Ken Sunshine, referring to photographers who often follow celebrities by car. "Unless somebody has the guts to carry this through legally, somebody's going to get killed through these chases."

Timberlake sought the restraining order July 7 against Artemus Earl Lister. Messages left at a number listed for Lister were not returned.

The singer has also filed a lawsuit in a London court against the British tabloid News of the World, which reported the singer cheated on his girlfriend, actress Cameron Diaz, with British model Lucy Clarkson, Sunshine said.

"Justin never met the woman in question, and we are confident a lot of money will be won for a wonderful charity when we win this case," Sunshine said.

Representatives for the paper have said they stand by the story.
