Whitney Way Thore
"My Big Fat Fabulous Life" star Whitney Way Thore was dating her distant cousin, Nathan, but she didn't know it until he told her during an outing at an aquarium. TLC

Since breaking up with boyfriend Lennie Alehat, dating life isn't going well for “My Big Fat Fabulous Life” star Whitney Way Thore. The body positive star went on multiple dates during Season 4, but she arguably had her strangest outing when she went to the aquarium with Nathan.

“Well, there's probably something I should share with you — very interesting information that I found out,” Nathan, whose last name wasn’t revealed, said in the sneak peek clip, which was obtained Tuesday by Us Weekly. Thore asked with a laugh, “What, did you go to a psychic or something?” To which he responded, “No, but I think we're distant relatives.”

Thore was shocked. “We are related,” Nathan continued. “We're, like, second cousins or something. I was telling my mom — she asked about the date, and I mentioned your name. … I forgot how the connection was, but she knew everybody's name, and she was telling me how we're tied together somehow in our family, and I was like, ‘What?’”

Thore was confused and even accused him of making up the being related information as a way to get out of dating her. When Nathan promised he was telling the truth, Thore said it was the weirdest date.

She told the cameras in a confessional: “I've been on some weird f--king dates before, but I've never dealt with this. … I feel like I entered into something that I would not have entered into had I had all the information — and I feel gross.”

Earlier in the season, Thore thought she might be pregnant with her ex-boyfriend’s baby. “Hey, guys. I just want to say thank you for all the congratulations and well wishes and everything that I got tonight,” the 32-year-old said wrote on Instagram in January. “It was really nice and I wish that I could answer your questions and talk more about it. But I can’t until next week, because I’m under a contract so I can’t. But anyway, thank you guys and I love you. I’ll see you next week. Bye.”

It turned out Thore wasn’t pregnant. She had a false positive after cysts grew on her ovaries. Like many viewers, Alehat was skeptical of the pregnancy. He asked to see the test and asked if the baby was his. The duo split during Season 3 after an apparent cheating scandal.
