Miley Cyrus and Liily drummer boyfriend Maxx Morando are fueling engagement speculations.

The couple, who appeared together on the red carpet of "Avatar: Fire and Ash" on Monday, Dec. 1, looked smitten as Cyrus sported a diamond ring with a chunky gold band on her ring finger. Cyrus contributed the track "Dream as One" to the movie's soundtrack.

For the movie premiere, Cyrus donned a sequined black Gucci dress with a silver necklace and matching earrings. She rocked her hair in her usual loose beach waves, while Morando kept his look classic with a black suit.

Reps for the couple could not be reached by USA TODAY at the time of publication.

According to Page Six, the jewelry designer of Cyrus' ring is Jacquie Aiche. Aiche's rep, Francesca Consulting, confirmed to the outlet that she custom-made the ring. On Instagram, Francesca Consulting reposted a photo to Instagram stories of the couple with the message, "Congratulations are in order for Miley Cyrus who just got engaged to Maxx Morando in a custom ring by @jacquieaiche."

In another photo, a shot of what appears to be a close-up of the singer's hand, showcasing the ring's details, was also shared.

The couple, who have been reportedly dating for over four years, just marked Cyrus' 33rd birthday together.

The singer and musician were first linked in 2021. Cyrus told British Vogue in June 2023 that they met on a blind date. "Well, it was blind for me and not really for him. I thought, 'The worst that can happen is I leave.'"

Cyrus was previously married to Liam Hemsworth, who confirmed his own engagement in October. The couple wed in December 2018, but Hemsworth filed for divorce less than a year later.
