The couple held hands and kept them in each other pockets and hugged each other in various public places.
However, it was also not the first time when Serena Williams and her boyfriend were noticed together.
He also often posts photos or messages in support of her on his Instagram account.
Talking to social media on 9 September, the 33-year-old sportswoman paid a touching tribute to the real love of her life- her sister Venus.Alongside a collage of the pair at different stages of their careers, she wrote: "She has my heart.❤️ Memories make my heart fill with more joy than I can express.A lifetime with @venuswilliams will not be enough."It is not surprising that Williams and her 35-year-old sister share a close bond having been raised on tennis as siblings growing up in Compton, California.And over the past 17 years they have battled it out on the court, as both rivals and partners.
