Ciara Holds Court at U.S. Open

After partying in Las Vegas and Atlanta over Labor Day weekend, Ciara chilled courtside at the 2011 U.S. Open in New York City on Monday (Sept. 5). A casually-dressed CiCi, along with director Spike Lee, Blake Lively, and Star Jones, cheered for her pal Serena Williams at the tennis match.

“Today was AMAZING!! US OPEN! @serenawilliams ROCKED! YEAH!” tweeted the singer after witnessing Serena defeat Serbia’s Ana Ivanovic 6-3, 6-4 in the quarterfinals.
