Not only because it's with another girl (Bella has come out as bisexual in the past), but because it's with somebody who had a little bit of beef with Bella not too long ago.
Meet 19-year-old YouTuber Tana Mongeau, who pretty recently made a video explaining potential drama between her and Bella.
While at the Electric Daisy Carnival (EDC) in Las Vegas in June, Tana made her way into a party, and had her sights set on Scott Disick, who was Bella's love-interest at the time.
Tana said she started “h*e dancing” to impress Scott, but instead got Bella's attention.
Bella “came out of nowhere” and starting dancing in front of Scott. “On occasion she hit a good [pose] and she’ll like, look at me like, ‘Yeah, b*tch. You see this?’ And I’m like, ‘I do, sister. I’ll give it to you.'”
However earlier this month, Tana tweeted that she was totally into Bella.
"i want to date @bellathorne next."
Well, it looks like they're on the right track!
