Kacie B. is going to be a bride! Two-time Bachelor contestant Kacie Boguskie announced Sunday, Feb. 16 that she is getting married to music executive Rusty Gaston.

"I cannot believe I get to MARRY my best friend," she gushed in a caption beside an Instagram pic of the newly-engaged couple holding up a "Mr. and Mrs." pillow. "I am so blessed to have such an amazing man!! I just want everyone to know!!!"

Nashville-native Boguskie, as Bachelor fans may recall, was twice-rejected -- first by winemaker Ben Flajnik and then by entrepreneur Sean Lowe during seasons 16 and 17 of ABC's reality smash, respectively.

Despite both seasons ending in tears for the reality contestant, Boguskie found love with Gaston, a producer at publishing studio This Music who's worked with stars like Blake Shelton and Celine Dion. "I have the best boyfriend in the entire world now," she told the Leaf Chronicle back in March 2013. "And he's a great Christian guy."

Gaston worked on Boguskie's engagement ring, featuring a large, circular-cut diamond, with jewelry designer Robin Haley: "It's beautiful!!!!!!" the bride-to-be gushed via Twitter. "Can't wait to see the band!!"
