Wearing the wrong accessories can cost you. That’s the kind of trouble Charlize Theron may find herself in. When it comes down to celebrity endorsements, always follow your contract. Swiss watchmaker Raymond Weil has filed a breach of contract lawsuit against the actress.

Weil says in court papers the South African-born actress signed an endorsement deal saying that from October 2005 through December 2006 she would only wear Weil’s high-end watches.

That deal allowed Weil to use Theron’s photographs in its advertisements in exchange for “substantial funds,” court papers say.

Meanwhile, says Weil’s lawsuit, the 31-year-old Theron, who also starred in “North Country,” “Mighty Joe Young” and “The Legend of Bagger Vance,” had an endorsement deal to promote a Dior perfume.

Details on what charity campaign got Charlize in trouble after the jump.

At a news conference on March 14, 2006, at a film festival in Austin, Texas, court papers say, Theron “was actually photographed wearing a watch from the Christian Dior line.” A photo of her wearing the watch is included as an exhibit.

The court papers also say, “Although the agreement clearly prohibits (Theron) from appearing in any advertisement for any jewelry, even for charity, she appeared wearing a necklace in an advertisement benefiting an AIDS charity, violating the agreement, from February 2006 to December 2006.”
