Bristol Palin Is Engaged — See Close-Ups of Her Ring and Adorable PDA!

It's an exciting time for the Palin family. On Saturday, Bristol Palin announced her engagement to Dakota Meyer, a former US Marine and Medal of Honor recipient. The couple shared their joyous news with a series of adorable Instagrams. "Truly the luckiest girl in the world, cannot wait to marry this man!!!!" Bristol captioned a photo of the pair kissing. She followed it up with a close-up of her stunning ring, expressing her excitement with heart emoticons in the caption. Dakota shared a photo of his own, writing, "I'm definitely the luckiest guy ever to be able to spend the rest of my life with @bsmp2 #shesaidyes." The proposal shouldn't come as a complete surprise to the couple's Instagram followers; they've posted several cute photos with her family, including her mom, former Alaska Governor and Republican vice presidential candidate Sarah Palin.

This will be Bristol's first time walking down the aisle, although she was formerly engaged to high school sweetheart Levi Johnston. Bristol and Levi rose to fame during the 2008 election, during which Bristol was pregnant with their son, Tripp Johnston. In 2010, Levi grabbed headlines when he posed for Playgirl. The following year, Bristol detailed their on-again, off-again relationship in her memoir, Not Afraid of Life: My Journey So Far. The Palins were back in the news last September following an epic fight at a party in Alaska. Read on to see pictures of Bristol's new chapter with Dakota, and then feast your eyes on the best celebrity engagement rings.
