Miley Cyrus and Stella Maxwell "could not keep their hands off of one another" as they enjoyed dinner together.

The 'Wrecking Ball' hitmaker and her Victoria's Secret model girlfriend, 24, looked closer than ever as they dined out at Cocina Condesa in Studio City, California on Monday (06.07.15) and were spotted giggling together over cocktails.

A source told US Weekly: "They could not keep their hands off of one another.

"[They were] whispering into each other's ears, laughing, smiling, and genuinely having a good time together."

Following their feast of guacamole, enchiladas, tacos and ceviche, Miley, 22, is said to have picked up the bill and gave Stella a kiss on the cheek as the pair vacated the eatery.

Rumours the pair had started dating first began circulating last week when Miley - who recently came out as bisexual - was seen locking lips with the blonde beauty in a car park close to the set of her new music video in Hollywood.

And although it was claimed that their make-out session was just a way to drum up publicity for the new video, friends have told TMZ that Miley is completely "in lust" with the model.

According to the website: "People who have been around them recently say the relationship is highly charged, not so much romantic as full-on lust."

Miley split from her ex-Patrick Schwarzenegger in March, and was previously engaged to Liam Hemsworth.

The controversial star also recently opened up about her experiences of dating both men and women, saying: "There are times in my life where I've had boyfriends or girlfriends. And there are times where I just love being with myself and don't want to give part of myself away to someone else ... I think that's a new freedom for women, especially."
