Things may not have worked out for 'Bachelor' contestant Kacie Boguskie on Season 16 (Ben Flajnik) and again on Season 17 (Sean Lowe), but perhaps it's for the best because the alum is now engaged to boyfriend Rusty Gaston.

Boguskie shared the happy-making news with a photo on Instragram accompanied by the adorable caption, "I cannot believe I get to MARRY my best friend @rustygaston. I am so blessed to have such an amazing man!! I just want everyone to know!!! #futuremrsgaston #bliss #love #mr&mrs."

She also retweeted a photo of her engagement ring that a friend shared the day after Valentine's Day (Feb. 15).

The couple have been dating for over a year. Congratulations to them both!
