Gabrielle's mom, to be played by Maria Conchita Alonso, is paying a visit to "Desperate Housewives."
In an episode tentatively scheduled for Feb. 19 on ABC, Alonso will play Lucia, who drops in on her daughter after leaving the latest in a string of husbands, the network said.
Gabrielle is played by Eva Longoria.
Lucia has been referred to previously by Gabrielle -- and not in the most loving way -- but hasn't been seen until now.
"She's extremely ecstatic and she loves the role," said Alonso's publicist, Rona Menashe. "She watches the show and loves it."
Alonso, who's filming the episode this week, made her U.S. movie debut in "Moscow on the Hudson" in 1984, playing opposite Robin Williams. Her other films include "The House of the Spirits" and "Chasing Papi," and she has appeared on stage and in TV series including "Kingpin."
The Cuban-born Alonso, who was raised in Venezuela and was a beauty pageant winner, also is a Grammy Award-nominated singer.
