NAMES IN THE GAMES : Ex-Girlfriend Sues Theismann

Actress Cathy Lee Crosby is suing her ex-boyfriend, Joe Theismann, for $4.5 million, claiming that the former Washington Redskins quarterback abandoned his promise to financially support her.

According to the suit, filed Wednesday in Los Angeles Superior Court, the couple agreed six years ago to “forever combine their financial resources . . . to financially support each other and to act in each other’s best interests as friends, confidants, companions and advisers.”

Crosby, who co-hosted the television show “That’s Incredible” in the early 1980s, said the couple “declared each other immediate family members,” in a will drawn up during their romance.

Crosby is also seeking a share of Theismann’s 9,200-acre ranch in St. Croix, Virgin Islands, and his condominium in South Bend, Ind., near his alma mater, Notre Dame.

Theismann couldn’t be reached for comment.
