For some fans, "proof" that Whitney and Lennie might be back together can be found in the handful of photos of them she has posted via Instagram. In one shot, Whitney, her brother Hunter, and Lennie are posing together next to a pair of palm trees from some tropical location. Another photo features Whitney and Lennie sporting '80s-inspired looks while filming for My Big Fat Fabulous Life.

On the Season 10 premiere, Whitney clarified that her relationship with Lennie was platonic.

"I just really want to clear up, though. Like, our relationship is not even weird. It's not even inappropriate," she told producers, before turning to Lennie. "Of course, luckily my boyfriend is very not jealous and very not worried about you at all. I showed him a picture of you and he was like, 'Oh, never mind. I'm fine.'"

Whitney also explicitly told Lennie that she was still dating her French boyfriend. And it was not an open relationship.

Fast-forward to Season 10, Episode 10, and that's exactly what ended up happening.

While on a vacation with her brother, Hunter, and friends, Lennie, Jessica, and Isaiah, Whitney revealed that she and the Frenchman decided to have a "don't ask, don't tell" policy — essentially opening up their relationship. She told producers: "The Frenchman and I, we're realistic about the amount of time we actually get to see each other physically. So we've officially loosened the bonds on our relationship physically. Just in the event of me maybe having a vacation adventure."

Since Whitney and Lennie shared a beachfront room on their vacation, viewers were left to assume he was her potential "adventure."

In Episode 11, Hunter told cameras, "I thought that maybe something would happen between Whitney and Lennie. But I didn't expect it on the first morning." Viewers also saw footage of Lennie and Whitney waking up in the same bed, hinting that things did end up getting physical between them (although both insisted they just slept).

Before leaving their St. Lucia vacay, Whitney and Lennie finally addressed their complicated relationship status during the MBFFL Season 10 finale. "I know that I love you ... I know that I love someone else too. It feels confusing sometimes," Whitney told Lennie — who reciprocated his feelings of love. The catch is: Are they "in love" with each other? Both answered, "I don't know," before sharing a kiss. (Which doesn't send mixed signals at all, right?)
