Jeremy Calvert sparked rumors of Brooke Wehr's possible pregnancy last week on Instagram.

Ahead of Halloween, the Teen Mom 2 dad shared a potential couples costume for himself and Wehr.

"[Perfect] costumes for us," Calvert wrote in the caption of the Instagram photo seen below, which features a "bun in the oven" inspired costume set.

Right away, fans assumed that this was Calvert's way of announcing that he and his fiancee, Wehr, were expecting. However, a short time later, Wehr confirmed that this was not the case at all.

"No people I am NOT pregnant. But don't worry if I ever am, you will be the first to know," she wrote on Instagram with a photo of a negative pregnancy test.

Calvert and Wehr began dating in early 2015 after Calvert and his first wife, Leah Messer, parted ways due to what he claimed was her cheating (which she denied). Then, after a brief split later that year, the couple got back together and over the summer, they became engaged during a trip to Ocean City, M.D. with his daughter, Adalynn, and her daughter, McKenna.

Although Calvert has made it clear that he does not want to continue to film for Teen Mom 2, he and Wehr are expected to appear on the series' upcoming season which will likely premiere sometime later this year or early next year. No word yet on whether or not their vacation engagement will be seen on the show.
