The elite tennis star has every reason to celebrate after beating Angelique Kerber, on 9 July to win her seventh Wimbledon and 22nd Grand Slam title. She also won her sixth Wimbledon doubles title with her sister Venus; their 14th major doubles title in all.

Williams has a good group of people to support her, especially her celebrity friends. While good friend Beyonce was in attendance, the 34-year-old athlete was particularly excited to meet Kate Middleton at Wimbledon, following her victory over Elena Vesnina in the women's semi-finals.

Serena recorded a video of herself, saying: "OK, so I'm in the 'In Crowd' now, I'm with royalty." The camera then pans over to show the tennis player posing with a smiling Middleton and Sophie, the Countess of Wessex.

Beyonce arrived at the centre court with husband Jay Z as Williams faced Germany's Kerber in the woman's final of the tournament. The power couple were seated in the player's box where they chatted with Serena's family. Let's not forget, Williams appeared in Beyonce's video for her smash hit Sorry, earlier this year. The pair are said to be great friends.

Meanwhile, the tennis player's love life may also be doing well. The star's rumoured boyfriend Alexis Ohanian took to Instagram to share a picture of Serena holding the Wimbledon trophy.

The pair have been dating since October 2015, after reportedly being introduced to each other at a lunch.

For those who don't know, Ohanian is the co-founder of popular website Reddit. The internet entrepreneur also started several other websites such as Hipmunk and Breadpig.

Williams has also been linked with singer Drake, rapper Common, Irish actor Colin Farrell, former NFL player Keyshawn Johnson, actor Columbus Short, actor Jackie Long and tennis coach Patrick Mouratoglou.

She sure knows how to pick them.
