"Teen Mom 2" star Leah Messer celebrated the 40th birthday of her boyfriend, Jason Jordan, by treating him to a special meal over the weekend. But, fans were shocked after discovering her new beau actually has a twin brother!

Messer posted a photo on Instagram on September 8 with a caption, "Dinner for these crazy twin brothers." She was sitting beside her boyfriend at Rocco's Ristorante in Ceredo, West Virginia, where they enjoyed a double date.

Jardon seemed to appreciate the gesture of her girlfriend as he also commented on the photo, saying: "Thanks for dinner babe. Had such a good meal and maybe just a few laughs."

Many of Messer's fans and followers on Instagram are convinced they could have been destined to have twins if ever they take their relationship to the next level in the future.

"Wow! So he's a twin?! Better think about whether or not you'll have children! Yikes, could you imagine another set of twins?" one follower wrote.

Prior to her Instagram post, Messer shared a photo of her and Jordan while hanging out with her daughter with a caption: "It's @raylansdad416 birthday! Happy birthday, babe!" She gushed. "I'm so grateful we have you! Our days are always filled with so much joy and laughter! You da best."

According to In Touch, Messer and Jordan became Instagram official on Aug. 6, and their relationship is blossoming and "getting serious." The "Teen Mom 2" star and mother-of-three met Jordan, who also has a son, through his cousin.

Messer and Jordan were also previously spotted enjoying their time at a beach in Florida together with their children. And although there is a 14-year age gap between the two, both of them still get along with each other.

When it comes to having a baby, Messer isn't sure about it yet as she's busy filming for "Teen Mom 2," and taking care of her three daughters. During her Q&A on her Instagram story, one of her fans asked her: "Do you want any more kids?"

She honestly responded to the question, saying: "I really don't know. I'm happy with my life rn and don't really think about it."

Messer shares eight-year-old twins Ali and Aleeah with ex-husband Cory Simms, while 5-year-old Adalynn with her ex-husband Jeremy Calvert. Jordan, on the other hand, n has a two-year-old son named Raylan with his ex-wife.
