Serena Williams reveals sweet proposal by her new fiancé, Reddit co-founder Alexis Ohanian

Ever since San Francisco-based Reddit co-founder Alexis Ohanian met and began dating tennis star Serena Williams in late 2015, the two have kept their relationship out of the public eye.

There's been a few public appearances and an Instagram post or two since they met in October 2015, but the newly-engaged pair have largely kept their private life almost entirely off social media.

However, that changed Thursday, when Williams took to her fiancé's site to give a few details about Ohanian's recent proposal to her.

In the subreddit titled r/isaidyes, Williams' verified account posted a photo with a short few words about how Ohanian popped the question, suggesting that he whisked her off to Rome (to a table where their "stars first collided"). As she says, he got "down on one knee, he said 4 words, and r/isaidyes."

Under Williams' posting, Ohanian — who uses the verified handle u/kn0thing — added, "And you made me the happiest man on the planet."
