The most well-known offspring of Sarah Palin, Bristol, is engaged. She shared the happy news on Instagram this morning (or whatever time it was in Alaska).

Bristol - who seems to be rocking some serious Kim Kardashian nails - shared the above photograph with the caption, "Truly the luckiest girl in the world, cannot wait to marry this man!!!!!"

She also shared a photo of her engagement ring.

According to Us Weekly, Bristol's fiancé is Dakota Meyer, a veteran of the Marine Corps and a 2009 recipient of the Medal of Honor.

Begin the countdown to the inevitable reality show.
