When it comes to champions, Serena Williams dazzles. With a total of 13 Grand Slam singles titles alone, Serena is arguably today's single most dominant force in women's tennis -- plus she's absolutely gorgeous (I probably don't need to tell you how much excitement her visit to our offices caused!). To celebrate her passion for nails (Serena has her nail tech's license and hopes ultimately to own a signature chain of nail spas), she "played doubles" with OPI to create her own line of OPI Glam Slam Nail Lacquers. First up (just in time for January's Australian Open) is Simply Smash-ing!, a glimmering gold-green that is just that. You'll find it in a twin-pack with Black Shatter for a look that serves up style.
