Are Tana Mongeau andNoah Cyrusmore than just friends after all?

Mongeau sparked speculation of a potential romance between the two on Tuesday when she referred to Cyrus as her “girlfriend” in a YouTube video.

“If I have a boo — I don’t know how to phrase this, I just like to test my friends sometimes,” she said. “I thought it would be a fun time to text Imari off of Noah’s phone to see if he would flirt with her back.”

Mongeau’s rep did not immediately return PEOPLE’s requests for comment. A rep for Cyrus could not be reached.

While this is the closest either has come to suggesting they’re dating, Mongeau did address romance rumors in September, saying the two were just friends.

“No I’m not in a relationship with Noah,” she said during an appearance on theZach Sang Show. “I do f—– love her though. She’s so dope. We actually have so much in common.”

“We’re really similar,” she added. “It’s cool because it caught me off guard.”

While the two still spend time together and present their relationship as romantic, Mongeau has said that they are in an “open” relationship.

“We are both very open people,” she said. “We are not in a place where monogamy is always easy.”

“It’s complicated,” she added. “But I guess you could say we are open.”
