Serena Williams would have invited all her family, her close friends including her great friend Eva Longoria, but also Meghan Markle and her boyfriend Prince Harry.
The actress stars as Rachel in hit USA show Suits, but is now looking at focusing her attention at other things.
Rumours that Prince Harry will soon propose to his girlfriend Meghan Markle gathered pace after the couple were photographed attended the wedding of Harry's long-time friend, Tom "Skippy" Inskip.
"Even before Harry, she was starting to think about transitioning out of acting", a source added. According to E! News, Meghan - who plays Rachel Zane - "wants to focus on other worldly endeavours she is passionate about, like her philanthropy".
Markle is known for her humanitarian work with the United Nations Women organization and World Vision.
The aforementioned Harry, of course, is Prince Harry, Markle's boyfriend, and the reason Markle has been under intense scrutiny since the couple started dating a year ago.
The 35-year-old star was born and raised in California, but she now lives in Toronto where Suits is filmed.
Meghan and her royal beau have been dating for almost four months after Kensington Palace confirmed their relationship back in November.
With Meghan now drawing more paparazzi attention than ever, the source said, she's "just keeping a super low profile right now". "Locals love her so much and she really engaged herself into the community when she moved here for "Suits" years ago".
She is now based in Toronto because of "Suits", but the publication was told that she is doing her best to keep a low profile.
A source said: 'Diana's jewellery collection was left in trust for the boys, and Meghan apparently loves emeralds. "She's just not as accessible now but she's always been so kind and genuinely so sweet to people around town".
