The Teen Mom 2 star, 26, shared a photo on Instagram of herself sitting with Jason at restaurant table. Jason man is seated next to his twin brother and his date!
"Birthday dinner for these crazy twin brothers," Leah wrote in the caption.
Fans were surprised to find out that Jason was a twin.
Messer has only been dating Jason for a few months, but looked very close to him as she beamed at the dinner table in a pretty blue dress.
Jason is 14 years older than Messer and as RadarOnline.com has reported, he once begged for drugs in a series of bizarre videos.
Messer and her beau are both parents.
And in an odd coincidence, Jason is a twin and the reality TV star shares twin daughters Ali and Aleeah, 8, with ex-husband Cory Simms. Messer also has five-year-old daughter Adalynn with her ex-husband Jeremy Calvert.
Jason raises a son Raylan, 2, with his ex-wife, according to The Ashley. Like Leah, Jason is also divorced and his divorce from his ex-wife was finalized last year.
In some other photos Messer posted on Instagram, Jason is shown playing with her youngest daughter Adalynn at a park.
"It's @raylansdad416 birthday!!! Happy birthday, babe!" Messer wrote in the caption. "I'm so grateful we have you! Our days are always filled with so much joy and laughter! You da sic best."
The blonde met Jordan through a friend who is his cousin, according to an Us Weekly insider.
Since then, Messer and Jordan have taken their romance to the beach, holding hands on the Florida sand.
"Even though he's older, they have a lot in common," the insider told Us about their age difference.
