After the photo was shared, a fan of Glanville suggest she let Best know that she'd like to hook up, and in response, Glanville told the woman, "He knows."

As the status of Glanville's possible romance with Best remains unclear, her Famously Single co-star, Aubrey O'Day, hinted that she wasn't the only one who struck up a romance during filming on the E! reality series.

"The show is about all of us coming together, dating, learning through a dating coach how to go out there and approach people that are better suited for us and kind of get over the issues that we were having. And it ended up just like becoming like this chemistry happened within the house with a few of the castmates, and Pauly and I were one of them," she told E! News.
