While announcing her new brand Florence By Mills Coffee in an April 13 Instagram video, Millie blew a kiss to her followers—flashing her halo diamond stunner in the process.
The actress gave fans their first peek at the sparkler just a few days before when she seemingly revealed the engagement news on Instagram by sharing a photo of Jake wrapping his arms around her as she wore a ring on that finger and they smiled from ear to ear. Borrowing a lyric from Taylor Swift's song "Lover," Millie captioned the April 11 post, "I've loved you three summers now, honey, I want 'em all."
Jake also appeared to share the news on his account by posting pictures of the couple and writing, "Forever." The two received an outpouring of celebratory messages, including from Millie's Stranger Things co-star Jamie Campbell Bower who dropped three hearts and a fire emoji.
Millie, 19, and Jake, 20, first sparked romance rumors in the summer of 2021 and made their red carpet debut as a couple in the spring of 2022. Since then, the Enola Holmes alum and the son of singer Jon Bon Jovi have continued to give fans glimpses into their relationship at premieres and on social media, with him calling her the "girl of my dreams" in a February birthday tribute.
"I love you more than words can describe," Jake continued. "Everything about you is golden down to the core."
