The tennis ace also made reference to her 2017 New Orleans wedding to husband Alexis, 37, when asked what had been the best kiss of her life.

Recalling their lavish nuptials, she said: ‘My wedding day with Alexis.’

The sports star also gave fans an insight into her likes and dislikes, revealing in the chart that she’s seen all of the Jurassic Park films, is obsessed with salty foods and wanted to be a vet when growing up.

Serena gave birth to Alexis Olympia in September 2017 in what was later revealed to be a traumatic birth which almost saw Serena lose her life.

The star was forced to have an emergency c-section to deliver her daughter Alexis Olympia after her heart rate started to plummet.

The day after the birth, Serena was experiencing a shortness of breath and scans revealed she had several blood clots in her lungs.

She was given a drip with anti-coagulant drugs, but constant coughing from her pulmonary embolism opened up the scar from the c-section and her abdomen filled with her now-thinned blood.

Doctors saved her life by inserting a filter into a major vein to prevent any more clots from entering her lungs, and she was put on bed rest for the next six weeks.

In October of last year Serena revealed on Insta Stories that little Olympia has been signed up for tennis lessons herself.

However she was to be instructed by neither her mother nor by her aunt Venus, according to Serena’s posts at the time.

In fact Serena shared that the teacher they have chosen at that point had ‘no idea’ that her new pupil is the daughter of a world-famous athlete.

She also said she would leave the lessons immediately after dropping Olympia off so as not to be an ‘overprotective’ or ‘distracting’ influence.
