Kate's pregnant sister has been pictured at the tournament several times in the past two weeks but chose to take her brother James Middleton on both occasions. "I'm trying to focus on my team and my box and trying to focus on the tennis", said Kerber.
There will be a couple of duchesses in attendance on Saturday.
Proving yet again that they'll make fantastic parents, Prince Harry was captured playfully telling off an Irish tot who cheekily grabbed at Meghan Markle's hair and face during their tour of Dublin. "She was interested and charming".
She went on to critique the fit - particularly cutting words, coming from a couture designer - suggesting her dress was too loose.
Serena gave birth to her first child, daughter Alexis Olympia Ohanian Jr, less than a year ago and if she wins Wimbledon, she'll be the first mother since 1980 to pick up the trophy.
Later on, the duchess made a quick change for a reception at the residence of Robin Barnett, the British ambassador to Ireland.
"Now she's supporting me in a different role". Markle and Middleton will attend the Ladies' Singles Final at Wimbledon on July 14, 2018.
'We always have supported each other, just been there for each other through a lot'.
Harry and Meghan are now settling into married life, and the pair have had a busy few days this week as they have made a number of appearances together.
According to Irish senator Catherine Noone, who was one of the key figures in the country's recent push to legalise abortion, Meghan told her that she was "pleased" the referendum had been a success.
Ever since he got married the pressure has been on to start a family, and Harry revealed his thoughts on it all while joking with a royal fan.
