Another Teen Mom OG wedding!
Just a month after Catelynn Lowell and Tyler Baltierra tied the knot, Amber Portwood's baby daddy Gary Shirley, 27, and his girlfriend, Kristina Anderson, 33, married in a top-secret ceremony, RadarOnline.com can confirm.
Sources exclusively tell RadarOnline.com that the parents of 6-month-old Emilee got hitched in Michigan, where the Indiana-based couple likes to vacation together.
Friends of the pair, who never announced an engagement, were puzzled by the hush-hush nuptials.
"Gary is a total loud mouth and tells everyone about his business," the source says. "So it's shocking he only told a few people, and made them promise not to tell a soul."
Insiders believe only close family members attended the small ceremony, which took place in late September.
Amber Portwood, the mother of Shirley's 6-year-old daughter Leah, and her fiancé Matt Baier heard about the wedding through rumors around her hometown, friends say.
"They can't believe it, because Gary never seemed that serious about Kristina," sources tell RadarOnline.com.
The big news was first reported by The Ashley's Reality Roundup.
As RadarOnline.com previously reported, Shirley and Anderson's relationship began under scandalous circumstances. The couple began dating in early 2013, while she was still married to husband Greg, the father of her eldest daughter, Karly, 8.
Greg filed for divorce on Valentine's Day 2014, and the split was finalized that April.
They fought over Kristina's intentions for Karly to star on Teen Mom OG, but they eventually came to a resolution out of court. The little girl has never appeared on the MTV show.
