Michael Phelps Just Scored Another Win – In The Game Of Love

Add one platinum ring to those 18 gold medals.

Olympic swimmer and all-around superhero Michael Phelps is diving into a happy new venture – marriage. Phelps and his girlfriend, former Miss California USA Nicole Johnson, announced their engagement in adorable corresponding Instagram posts last night.

"She said yes," Phelps wrote, followed by numerous smiley emoticons.

"I'm gonna be a Mrs.," countered Johnson, with a shot of the two gazing at each other lovingly while lying in a snow-dusted field.

Wow, check out that massive bling – you can see it front and center in both wide shots! Need we state the obvious, Nicole? We're jealous. Oh-so-jealous.

This welcome happy news comes on the heels of a rocky 2014 for Phelps – the most decorated Olympian of all time, with 18 gold medals – who checked into rehab after receiving a DUI in October. We've been rooting for him, and we're beyond thrilled to see he's bouncing back – we're certain this will be his best year yet!
