Miley Cyrus and Maxx Morando are engaged after four years of dating

Miley Cyrus is engaged to Maxx Morando.

The 33-year-old actress and the 27-year-old singer recently got engaged after four years of dating, according to the New York Post newspaper's Page Six column.

The loved-up couple sparked engagement speculation earlier this week when they walked the red carpet at the Los Angeles premiere of Avatar: Fire and Ash.

Miley and Maxx posed for photos at the premiere, where the chart-topping star was seen sporting a diamond set in a thick gold band.

Francesca Consulting, Miley's representative, subsequently confirmed that designer Jacquie Aiche custom-made the sparkling engagement ring.

Francesca also revealed additional details about the ring, confirming that Miley was wearing a "chunky" 14-karat yellow gold band.

Maxx’s dad, Dan Morando, has already posted a congratulatory message to the couple on social media. However, neither Miley nor Maxx have made any public comments about their engagement.
