Olivia Palermo and Johannes Huebl are engaged! Olivia showed off her engagement ring [1] in an Instagram video Johannes shared on Wednesday following their PDA-heavy beach day in St. Barts over the weekend. The couple soaked up the sun on their annual French vacation, lounging on the beach as Olivia displayed her incredible bikini body and Johannes flexed his muscles in the water. They were seen getting cozy on a towel, holding hands, and sneaking kisses across the beach, enjoying the gorgeous weather — and each other! It's no wonder Johannes was inspired to pop the question. Olivia closed out 2013 with a sexy bikini look — check out some of her other best outfits from the year that was [2].
