Ariana Grande and Mac Miller seem to take their relationship into greater heights as they publicly exchange sweet kisses over a Japanese dinner in Encino, California on Sunday.

TMZ’s report shows intimate photos of the two famous artists in Katsu-Ya restaurant. The singer and the rapper, both dressed in their comfortable casual clothes, were caught kissing in between their meal. Witnesses claimed that Ariana was even lying on Mac’s lap.

When asked about rapper Mac Miller, Ariana played coy in an interview with E News at the launch of her new MAC cosmetics Viva Glam lipstick campaign.

"He's the best," she said. "It's always dope making music with him."

But when asked about their rumored romance, Ariana laughed and diverted the topic.

"I love my MAC lipstick," Grande told. "This is the only Mac I'm here to talk about today, girl!"

Grande and Miller first got together to record the famous “The Way” more than three years ago. The music video shows their steamy smooch which made fans speculate about their special relationship.

However, during an April 2013 interview with MTV News, the hip-hop star denied the rumors linking him to the Nickelodeon alum, according to Us Weekly.

“That's the homey. She's got a boyfriend (Jai Brooks) and everything," he explained. "Obviously, that [kiss] made everyone talk. I didn't even know that was going to happen and then we were shooting and the director was like ‘This should happen’ and I'm like ‘Alright’.”

The rumored couple had a sexy performance at the Nikon Theater at Jones Beach in New York, at the Billboard Hot 100 Music Festival last weekend. They were dancing closely to each other and looking into each other’s eyes during their number.

There’s no better way of admitting the truth than avoiding the issue and let their obvious actions speak for them, right?
