The Neighbors star's sister, Danya, also wasn't thrilled about their mother's tweet, writing: "Seriously. I actually gagged."
"It's gnarly," Seth replied to his sibling.
Mindy Kaling, however, fully supported Sandy's tweet. "I love it," she wrote to Seth, her longtime friend, "And I don't want you to dissuade her." The 35-year-old actor responded, "I don't think I can."
Seth might be embarrassed about his mom's tweet, but he isn't shy about making jokes in regard to his own sex life. Just last month, he quipped with ET that he and his wife, Lauren Miller, would totally be down to have a fling with Justin Timberlake and Jessica Biel. "We should have a foursome live on stage!" he exclaimed while at the Hilarity for Charity event. "Perfect!"
