A Law & Order: SVU fan apologizes for not properly fangirling over Mariska Hargitay and Ellen Burstyn after spotting them in real life. The fan’s husband and stepson missed Burstyn’s presence while being starstruck by Hargitay at a farmer’s market in NYC. Burstyn plays Stabler’s mother on the show, making her Hargitay’s on-screen in-law. Hargitay was also seen wearing a Taylor Swift sweatshirt, as she is friends with Swift and inspired the name of Swift’s cat Olivia. Fans are eager to see more of Burstyn on the show.
