On Rules, former Less Than Perfect star Rue will recur as Brenda, Jeff (Patrick Warburton) and Audrey (Megyn Price)’s new surrogate. In a November sweeps episode, Dynasty alumna Collins will play Bunny Dunbar, the mother of Russell Dunbar (David Spade).

Russell's mother had more potential, she should have imitated some of his stuff to see where he got his style from, instead of this gift-giving agenda. And I guess Joan Rivers would have been a better choice for the role.:p
