American tennis star Serena Williams has stressed that communication between partners is very important to keep a relationship going. Williams, who got married to Reddit co-founder Alexis Ohanian in 2017, said her relationship works because they both put the effort to keep things afloat.

According to UK’s entertainment website, Female First, speaking in a video for dating app, Bumble, Williams said: “Marriage is not bliss. But it can be if you work at it.” The former World No. 1 said the deal breaker in any relationship is not having loyalty.
