Miley Cyrus' romance with her rumored girlfriend Stella Maxwell is heating up. After recently being pictured kissing at a Beverly Hills parking space, the couple was spotted enjoying another PDA-filled moment at newly opened restaurant Cocina Condesa in Studio City, California on Monday, July 6.

An onlooker told Us Weekly that the "Adore You" songstress and the Victoria's Secret Angel were seen holding hands when they arrived at the restaurant. During the dinner date, the couple enjoyed some of Executive Chef M. Elena Vega's tastiest dishes including tacos, ceviche, enchiladas, street corn and guacamole. They also sipped on cocktails by Gilbert Marquez, the Mezcaleria's executive mixologist.

"They could not keep their hands off of one another," the eyewitness said of the lovebirds. They were also seen "whispering into each other's ears, laughing, smiling, and genuinely having a good time together."

The source further said that Miley picked up the bill at the end of the evening meal. It's also said that Miley planted a kiss on Stella's cheek before they stepped out of the expensive eatery.

Miley and Stella started out as mutual friends through social media. "We met through Grindr..." Stella jokingly told V Magazine. "Nah, joking. We met through mutual friends via Instagram, which is where Cheyne [Thomas] contacted me about taking some photos. It's been a trip to hang out and see a little of their world. Felt very organic and right."

They have been rumored dating since last month. The pair fueled the reports when they were seen checking out of an NYC hotel together before later being spotted making out on the set of Miley's new music video.
