Matthew Koma revealed that his wife, Hilary Duff, had sex with him while he was wearing the “sweaty” shirt he performed in at Lollapalooza.
Duff, 37, took to Instagram on Monday, August 4, to share a video of Koma, 38, hanging out in a white cutoff tank top, which he paired with a green baseball cap and black shorts.
“Pretty cool that you’re still wearing your shirt that you performed in yesterday at sweaty Lollapalooza and you flew home in, and you’re well into this day,” she quipped. “Also having a pretty intense nip slip right now.”
Koma, who performed at the Chicago music festival with his band Winnetka Bowling League, poked fun at Duff, saying, “You had sex with me in this shirt. What’s that say about you?”

How you’re able to be the mom, individual, wife, spirit, and tie dye influencer you are, while making it look so easy is mind boggling and I don’t know what I did right to deserve being on the receiving end of it. Thank you for being the most steady, supportive, empathetic, loving, and passionate. You make me so much better. You make our family what it is. You’re the only thing that makes me cry through the Prozac. I love you.”
