"Law & Order: Special Victims Unit" will feature three star-studded episodes this spring with actor, producer and musician John Stamos, "Law & Order: Los Angeles" star Terrence Howard and Golden Globe Award-winning actress Lori Singer as guest stars. Oscar, Emmy and Tony Award-winning actor Jeremy Irons and series alum Diane Neal will also return to make a guest appearance in the upcoming episodes.

Stamos will appear in the episode titled "Bang," as an adoption attorney with a secret passion. Stamos returns to NBC after his four-year tenure on the Emmy Award-winning drama "ER." In addition to appearances on "Glee" and "Entourage," he is most well known for his roles on "General Hospital" and "Full House." Singer will join Stamos in a rare television appearance, assuming the role of a new mother who is struggling with her increased responsibilities. Singer, who won a Golden Globe for "Shortcuts" and was nominated for an Indie Spirit Award for "Trouble in Mind," is best known her performances in "Footloose," "Falcon and the Snowman" and NBC's "Fame."

Howard will make his guest appearance in the episode "Reparations" as part of a crossover episode between "Law & Order: Los Angeles" and "Law & Order: Special Victims Unit." Howard is most well known for his performances in "Crash" and "Hustle & Flow," the film that garnered him an Oscar nomination and a Critic's Choice Award for Best Song. He will be joined by former series regular Neal, who will reprise her role as A.D.A. Casey Novak for the first time since her departure from the show in 2008.

Irons, who appeared as a guest star in an episode earlier this season, will reprise his role as Captain Jackson, a psychologist that worked with the SVU team. The episode, titled "Totem," will showcase the first case in series history to feature a solo female perpetrator responsible for sodomizing and murdering her victim.
