Alexis Ohanian says his fiancée Serena Williams will be an "awesome mom".
The 35-year-old tennis player is set to welcome her first child into the world with the Reddit co-founder and is excited to see her become a mother.
He told CNBC's Squawk Box show: "She's very good at a lot of times and well on her way to being an awesome mom too ... At Reddit, it's really important for us to support men and women when they are welcoming a new member to the family and so we have a pretty generous parental leave policy.
"I'll be taking off for six weeks myself and trying to do the best job possible as a new dad, a first-time dad ... We want to break that stereotype that the men work and the women take care of kids. We want to give that opportunity to everyone."
Meanwhile, Serena previously admitted she "doesn't know what to do" with a baby.
She said: "It just doesn't seem real. I don't know why. Am I having a baby? If you would have told me last year in October or November that I would have a baby, not be pregnant but have a baby, I would have thought you were the biggest liar in the world.
"This is kind of how I am right now. This is happening sooner than later, and it's going by so fast. I don't know what to do with a baby. I have nothing ... I've done absolutely nothing for the baby room."
And Serena couldn't believe when she found out she was pregnant, especially because she had big plans for her career this year and was on the cusp of playing in the Australian Open - a tournament she went on to win.
She added: "I did a double take and my heart dropped. Like literally it dropped.
"Oh my God, this can't be - I've got to play a tournament. How am I going to play the Australian Open? I had planned on winning Wimbledon this year."
