Serena Williams has been craving vegetables during her pregnancy

Speaking in an Instagram video, the Reddit co-founder said: "It's Friday night, I'm at Publix, going shopping 'cause my fiancé has cravings. I was told there would be cravings. I was not told they would be these. Zucchini, asparagus and … what's this one called again? Artichoke. There we go. Really? There are her cravings. It's amazing.”

And Alexis captioned the footage - which was published to the site on Saturday (19.08.17) - with a series of disgruntled and vegetable based emojis.

He also wrote: “I was told there would be late-night cravings.”

Meanwhile, the tennis superstar recently revealed she doesn’t think she's a “baby person” and isn't sure what she’ll be like as a mother, as prior to getting pregnant she didn't see herself as someone who would enjoy being around a young baby.

She said: "The biggest thing is that I don't really think I'm a baby person. Not yet. That's something I have to work on. I'm so used to me-me-me, taking care of my health, my body, my career. I always ask, 'Am I going to be good enough?'"

And the sporting star is "nervous" about the process of giving birth to her child, and has already decided she wants to have an epidural - in which doctors inject anaesthesia into the back to numb the area - when she goes into labour.

Serena said: "I'm nervous about childbirth. I'm not a spring chicken. The one thing I really want is an epidural, which I know a lot of people are against, but I've had surgeries galore, and I don't need to experience any more pain if I can avoid it."
