What better way to spend Labor Day than sitting in the stands and watching a good ol' tennis match?

Blake Lively and Ciara, looking end-of-summer splendid, attended the 2011 US Open at Billie Jean King National Tennis Center in NYC yesterday.

Having a family day out, Spike Lee was also on hand, joined by his son, and Boston Celtics player Kevin Garnett watched the match with his own family.
