The event was to raise funds for the charities the royals support, namely Harry's Invictus Games Foundation, helping injured military personnel. And it was the way the 37-year-old was holding her baby that pissed the people online.
"The Duchess was greeted by AELTC Chairman Philip Brook at the Players' Reception on arrival before making her way to No.1 Court, and it was always the intention that the visit would be only for the one match".
Co-host Susanna Reid added that she was "much more sympathetic" towards the royal couple wanting privacy, but felt that as Meghan was in a public place she should expect photos to be taken.
She brought along their adorable eight-week-old son Archie, but the way she was carrying him was criticised by some people.

Nadal began in the same vein here, leaping into the air when he broke the Querrey serve in the third game. But Centre Court is very much Federer's territory and the 37-year-old is looking as unsafe as ever.
The 23-time grand slam victor said she avoids reading anything about the duchess in the press. Also featured: Prince William and Kate Middleton; Prince Charles and Camilla, Duchess of Cornwall; and Meghan's mom, Doria Ragland.
All that said, Meghan Markle and Prince Harry seem to have been over the moon ever since expanding their little brood. Big day! It's the first time we've seen the families all together since Archie Harrison Mountbatten-Windsor was born. "The latest being she can't hold her own baby properly".
Something tells us the Sussexes know what they're doing when it comes to this whole parenting thing, and we couldn't be happier for this sweet family of three. The E! News chief correspondent said: "I would question this decision, the reason being that if any member of the Royal Family shows a preference towards one media outlet, it can get the others' noses out of joint".
Royal commentator Victoria Arbiter also weighed in on the criticism in a series of tweets.
She said that the young royal won't be "paraded" on the tour as Prince Harry "doesn't want him to grow up with the burden he did".
