Q: My mother and I have a disagreement about whether Mariska Hargitay, who plays Det. Benson on “Law & Order: SVU,” also played Cynthia the desk clerk on “ER.” Cynthia was the character who got involved with Dr. Green. I say she did, but my mother thinks she didn’t. — N.A.R., Las Vegas, Nev.

A: This time you’re right. Hargitay, the youngest daughter of body builder Mickey Hargitay and actress Jayne Mansfield, played both roles. She was Dr. Green’s needy girlfriend Cynthia Hooper on “ER” during the 1997-98 season. Early in her career, Hargitay was on the nighttime soap “Falcon Crest” as Carly Fixx. She turns 39 on Jan. 23.
