Dove Cameron has got engaged to Damiano David.

The Descendants actress and the Maneskin frontman sparked speculation they were set to wed back in October when they were photographed in matching black outfits in Sydney, Australia, and the 29-year-old beauty was spotted with a diamond on her ring finger.

And now, she has showed off her engagement ring in a series of photos of herself and the 26-year-old rocker on Instagram.

She wrote on the post, which included close up shots of the jewellery: "My favourite part of being alive [diamond ring emoji] happy new year.(sic)"

The couple marked their second anniversary together back in October.

At the time, the former Disney Channel star shared a carousel of photos and wrote on Instagram: "The best two years of my life.

"I am brought to tears at least once a week because life has become so beautiful with you in it. i love you in a way no words could ever express, but i will never stop trying. buon anniversario amore mio."

Last February, Dove explained why she and Damiano decided to go public with their romance after several months of dating.

She told People magazine: "We had a conversation early on, because it's a weird thing that you have to talk about.

"He was like, 'If someone in high school, or who's a lawyer, nurse or working at a coffee shop can post a picture of their partner and share the normal, beautiful parts of their lives, why should it be different for us?' "

The singer-and-actress admitted she felt "so much anxiety" about letting her relationship come under public scrutiny.

She said:

"I've been public in the past,, and I've had some not-so-public relationships that I was a little bit less inclined to share. Not because of the people I was seeing, but because it just felt like a scary thing to be really open about. It's like I got scared."

Meanwile, Damiano recently gushed about being "so in love" with his partner.

He said: "I'm so in love. We play each other's music, and I would say that we are very lucky because she loves music and I love her music. I really vibe with it. So it's very fun."
