Matt Winkelmeyer/Getty While the two have managed to keep their relationship private, they have occasionally stepped into the spotlight. In 2021, the artist shared a photo of Olsen on his Instagram. That same year, they made their red carpet debut as a couple. Jon Kopaloff/WireImage The Full House alum and her twin sister Mary-Kate Olsen in June 2021 spoke about keeping their personal lives out of the spotlight since their days as child stars, which they said is reflected in their minimalist style. "We were raised to be discreet people," Mary-Kate told i-D at the time when asked about their fashion label The Row's discreet, modest style. "I think that potentially that's just our aesthetic, our design preference," added Ashley, who along with Mary-Kate are the older sisters of WandaVision star Elizabeth Olsen. "But that doesn't mean that we don't also appreciate something truly ornate or maximal." "Sometimes a collection even starts quite like that, and then gets pared down," she continued. "It doesn't always start from that simplistic place."
