Those on hand at Flushing, N.Y., included former United States President, Bill Clinton, who enjoyed a warm hug with the 17-time Grand Slam champ after the match. The prez was so excited he almost didn't want to let go, as her sister Venus intervened and bailed Serena out.
"The Wolverine", Hugh Jackman was also in the Big Apple to take in what was a very entertaining match - sorry, ladies and gents, he was accompanied by his wife Deborra-Lee Furness.
Showing up to support the American were actress Eva Longoria, singer/Broadway actor Ricky Martin, and of course - the most famous Patrick in sports today - boyfriend/tennis coach, Patrick Mouratoglou.
Serena's BF watched proudly as his sweetheart successfully defended her Flushing Meadows title and was crowned queen of "Gotham City" for the fifth time in her career.
Williams currently sits in sixth place in tennis' all-time list for most singles Grand Slam titles, but should be moving up the ranks early next season.
Although she trails Martina Navratilova and Chris Evert (18) by one, Helen Wills Moody (19) by two, Steffi Graf (22) by five and Margaret Court (24) by seven GS titles, many consider her the greatest tennis player of all-time.
