Serena Williams has announced that she is engaged to Reddit co-founder Alexis Ohanian.

The tennis champ made the announcement, of course, on Reddit, in the form of a poem.

Serena Williams, 35, said Alexis Ohanian took her to Rome, where they first met, to propose to her – and she said “Yes”.

It caps off a year in which Serena Williams won her seventh Wimbledon singles title and 22nd Grand Slam singles title, but dropped to world number two ranking.

Reddit is a social media platform where users group around topics, news articles and discussion points, rather than around people they know in offline life.

Alexis Ohanian, 33, founded Reddit in 2005 alongside a college friend, Steve Huffman.

Serena Williams posted to r/isaidyes, a forum where users share their stories of wedding proposals, saying he had taken her to the table in Rome where they first met, where he got down on one knee and “said four words”.

One Reddit user responded by joking that the score was love-love.

Alexis Ohanian and Serena Williams had kept their relationship quiet on social media and in the world of celebrity gossip, but rumors began to circulate last year that they might be romantically linked.
