Mid-aughts alert!
Hilary Duff and Joel Madden famously dated from 2004 to 2006, but they've now reunited 16 years after their romance went kaput.
Over the weekend, the exes were joined by their spouses, as well as others, for a group dinner date in Los Angeles.
On Sunday, a photo started making the rounds on Twitter of a star-studded dinner at Scratch|Bar & Kitchen in Los Angeles that included, Hilary, her husband Matthew Koma, Joel, his wife Nicole Richie, Fall Out Boy's Pete Wentz, his girlfriend Meagan Camper, and record producer Josh Abraham and Gina Abraham.
In posting a photo of the guys from that evening to his Instagram Story, Josh joked, "New band alert."
Clearly, a lot of time has passed since Hilary and Joel dated, and they seem to be on good terms with each other.

Back in 2016, Hilary briefly spoke about the romance on Nico Tortorella's podcast "The Love Bomb."
"It was so all encompassing," she said of the relationship. "It was so intense. It was my life. It was like every minute of my day."
After Joel and Hilary split, he began dating Nicole, whom he married in 2010. The two share two children, daughter Harlow, 14, and son Sparrow, 12. Hilary, meanwhile, married hockey player Mike Comrie in 2010. The two finalized their divorce in 2016. In 2017, she and Matthew began dating, and they married in 2019. They share two daughters together, Banks, 3, and Mae, 10 months. The "Lizzie McGuire" star also shares a son, 9, with her ex-husband.
