"They are just seeing where things go now and getting to know each other," the insider added. Previously, a report by TMZ showed Grande, and Miller engrossed in conversation at the Katsu-Ya restaurant in Encino. The 23-year-old singer was seen "kissing and giggling" and even lying on Miller's lap at one point.

The Dangerous Woman singer previously gushed about Miller at the launch of her new MAC cosmetics Viva Glam lipstick campaign. She said, "He's the best. It's always dope making music with him."

Grande added, "I love my MAC lipstick. This is the only Mac I'm here to talk about today, girl!" The singer broke up with dancer Ricky Alvarez in July, after dating for a year. A source told E! News at the time that the Break Free singer was "happy to be single and do her [thing] for a little while".

The source went on to add, "She broke up with him. He didn't cheat or anything, they just found it difficult to make it work. They are still friends though."
