So awkward!

My Big Fat Fabulous Life star Whitney Thore thought she had a chance at getting back together with her ex-boyfriend Lennie Alehat after believing she was pregnant with his child. But once she confirmed that the pregnancy was a false alarm, the reality star had to endure another heartbreaking situation — coming face-to-face with his new girlfriend.

“[That feeling when] your ex bf brings a new girl to your party and you’re dressed in drag,” she captioned a photo of herself frowning on Instagram.

The 32-year-old wasn’t expecting Lennie to move on so quickly, especially since he had recently gone shopping for a crib with her. But when she invited her ex to a cocktail-themed housewarming party — where guests were asked to dress up like a popular drink — on the Feb. 14 episode of the TLC series, the dancer, who was rocking a fake mustache, was mortified when Lennie walked in with his date, who was wearing a sexy Bloody Mary ensemble.

“If you’re going to bring a date, couldn’t she at least be like missing some teeth?” Whitney joked in her confessional.
