The stars of the WTA - and ATP World Tour - came out for the China Open player party on Monday night.
One of the star guests was Serena Williams, who was actually the China Open's first winner in 2004.
Williams is the No.1 seed this year and heavy favorite after No.2 seed Victoria Azarenka was ousted.
Agnieszka Radwanska is the next-highest seed, at No.3. She is pictured with sister Urszula Radwanska.
One of the very best doubles teams in the world, Raquel Kops-Jones and Abigail Spears, was also there.
Caroline Wozniacki, Daniela Hantuchova and Jelena Jankovic all glammed up for the big celebration.
As did China's own Peng Shuai, Bojana Jovanovski and two-time China Open champion Svetlana Kuznetsova.
ATP World Tour No.1 Novak Djokovic has never lost in Beijing - three prior appearances, three titles.
And now for a few cinematic black and white shots - first, Germany's No.3 player, Mona Barthel...
As mentioned, Kuznetsova is a two-time champion here - but she's also the only two-time champion here.
The Radwanska sisters at the party. Big sister Aga won the Premier Mandatory-level event in 2011.
She has won six of her 13 WTA titles in the Asia-Pacific region, including all three of them in 2013.
Radwanska's good friend Wozniacki has also conquered Beijing before, winning here back in 2010.
Urszula Radwanska hasn't won here but sprung an upset already this week, over No.16 seed Simona Halep.
Daniela Hantuchova recently made her first Grand Slam quarterfinal in over five years at the US Open.
German No.1 Angelique Kerber is fresh off her second final of the season, finishing runner-up in Tokyo.
