The "7 Rings" singer filed for divorce from the real estate agent on Sept. 18 after over two years of marriage, with Dalton submitting his own paperwork soon after.
"They were taking their time together to slowly work through the details of the agreement privately before filing," a source tells E! News. "They've been really caring and respectful of one another every step of this process. It's been a very kind and patient uncoupling process."
The insider also noted that both Ariana and Dalton they have "moved on."
According to TMZ, who was first to report the filings, Ariana listed "irreconcilable differences" as the reason for their split, while the duo's date of separation is listed as Feb. 20, 2023, in the docs.
Reps for Ariana and Dalton have not publicly commented on the divorce proceedings.
However, the source added that Ariana and Dalton still "remain friends."
Amid news of her split, Ariana has been spotted without her wedding ring during an outing at the Wimbledon 2023 tennis championships. She also deleted images of her private wedding ceremony to Dalton, including a close-up of her custom Vera Wang gown.
Ariana and Dalton tied the knot in May 2021 at her Montecito, Calif. home. At the time, a source told E! News, "It was a beautiful day and very romantic. Everyone is happy for them. It was perfect and just what Ari wanted."
Prior to getting married, the actress had dated Dalton since the height of the coronavirus pandemic. After sparking romance rumors in early 2020, the pair made their relationship music video official when he appeared in the music video that May for "Stuck With U," Ariana's collab with Justin Bieber.
"They run in the same circle," a source close to the singer told E! News at the time. "He used to be a dancer and they have many mutual friends. She's gotten to know him quickly with the quarantine. They've been spending a lot of one-on-one time at home."
