Quickies: Ciara, Rihanna

Ciara and husband Russell Wilson were among several celebs spotted at the U.S. Open on Sept. 2, cheering on Serena Williams. They were guests, sitting in Serena’s box in Arthur Ashe Stadium in New York City. Along with other fans, including a slew of fellow celebs, the couple cheered on the tennis star as she faced off against Ajla Tomljanovic but lost the match. Ciara later tweeted to her friend and thanked her for her inspiration.

Rihanna jumped in to help a New York City restaurant staff clean up after a girls night out. The group had asked them to stay open past closing time and she decided to return the favor. A source told Page Six that she arrived at the caviar bar with a group of six girlfriends and were there until 2 a.m.
