Charlie Puth may have just declared a big change in his relationship status.

The "Attention" singer and his partner Brooke Sansone sparked speculation that they got married in private when they stepped out with what appeared to be matching gold bands on their wedding ring fingers Sept. 15.

Chartering a boat at Lake Como in Italy, the couple had rings on their left hands as they took a cruise around the romantic locale, which is a hotspot for honeymooners.

For the nautical occasion, Charlie, 32, aptly rocked a blue-and-white striped shirt and white pants, while Sansone, 25, donned a cherry print dress and matching kitten heels.

E! News has reached out to Charlie's reps for comment but hasn't heard back.

The sighting comes two weeks after Brooke shared a series romantic still life photos, with one image featuring lyrics from Don McLean's "And I Love You So" handwritten on the back of an envelope, reading: "The people ask me how / how I've lived 'til now / I tell them, 'I don't know.'"

The model also included a picture of another envelope decorated with white lace and a ribbon bow, as well as a snapshot of gifts wrapped in red-and-white striped paper.

The cryptic post came nearly one year after Charlie announced their engagement, sharing that he specifically flew to New York to propose.

"She said yes," the musician wrote in a September 2023 Instagram post, alongside a photo of his fiancée flashing her pear-cut diamond engagement ring. "I am the happiest, best version of myself and it is all because of you Brookie."

Charlie added at the time, "I love you endlessly forever and ever and ever."

Less than three weeks after the announcement, Brooke shared she had already started the wedding planning process, posting photos from a wedding dress boutique and a custom lipstick engraved with the words "Mrs. Puth."

She added in the caption, "bride to be."
