Ed O'Neill has added his name to a lawsuit filed by five of his Modern Family co-stars against TV studio bosses on Tuesday in a dispute over their contracts.

Sofia Vergara, Jesse Tyler Ferguson, Eric Stonestreet, Julie Bowen and Ty Burrell claim their current long-term deals with 20th Century Fox TV are in violation of California labor laws, which state personal service contracts can last no longer than seven years.

They are asking a judge to declare their prior agreements null and void, allowing them to renegotiate fresh contracts with increased salaries.

Co-star O'Neill was not part of the action, but on Thursday an amended complaint was filed.

According to The Hollywood Reporter, O'Neill wants his deal declared "illegal" because of the alleged labor law violation.

Due to the lawsuit filing, a cast table read-through was scrapped on Tuesday, but the stars are said to have reunited on Thursday for the postponed get-together.
