Serena Williams and OPI have paired up (it's so hard to avoid a tennis reference!!!) to create a line called Grand Slam. The first offering in the collection is Australian Open, which consists of Simply Smashing and Black Shatter (shown below), a topcoat that creates a crackled effect. It goes on sale in January 2011, which is a shame, because it would have been great to have for the holidays. Three more duos are set to be released: French Open 5.11, Wimbledon 6.11 and U.S. Open 8.11.
