Tana Mongeau is sparking those romance rumors once again between her and Noah Cyrus.
The 21-year-old viral video star's most recent YouTube post was titled "i took my girlfriend's phone and flirted with my best friend. prank????," leading many fans to speculate as to whether the ladies are an item. "Sorry Noah. sorry Imari," Tana captioned the video. "I'll go back to being crazy by myself."
In the video, Tana takes Noah's phone and sends messages to their pal, Imari, as if she's the 19-year-old singer. Noah is seated next to her while she texts Imari.
ET has reached out to Noah and Tana's team regarding the "girlfriend" comment, but after the video was posted Noah took to her Instagram Story to seemingly address the rumors.
"Guysssss. we are FRIENDS. relaxxxxxxxxx," she posted.
Back in September, Tana's husband, Jake Paul, addressed the rumors between Noah and his wife after they were very flirty on Instagram. He confirmed that he and Tana -- whom he married this past July in Las Vegas -- are in an open relationship.
As for whether Tana and Noah were "hooking up" at that time, Jake told ET Live's Denny Directo and Cassie DiLaura, "So, I think Noah's wanting to hook up with Tana."
"Since the start of our relationship, it's been, like, an open type of thing because that's just how we both are," Jake, 22, said of his relationship with Tana. "And then Noah and Tana are, like, wanting to hook up and I think Noah's the one pushing that narrative, which I think is dope, again."
When asked if he would take issue with the ladies hooking up, Jake insisted he would have no problem with that, adding, "Yeah, especially if I could be there."
He then addressed Noah directly, declaring, "Goddamn girl, where you at?"
After ET Live's interview with Jake, Noah took a screenshot of the discussion and posted it to her Instagram Story and joked that Jake was not invited to "be there."
In addition to the romance rumors between Tana and Noah, Jake also admitted that he and Tana have yet to get a marriage license. Tana later insisted the two were legally married.
"I think it happened so fast because we just wanted to do everything so fast, and I don't think being married on paper is the same thing as just being married in general," he explained. "I don't think a paper means you're married."
Jake then joked, "I don't think so ... because we're probably gonna get divorced eventually."
