After creating her first successful collection of nail polishes last year, Serena Williams is releasng four brand new shades for her O.P.I. Glam Slam! collection. The new lineup includes a silver hue named Spark de Triomph, a gold-flecked Rally Pretty Pink (inset), as well as a Shatter shade in new white and red variations, which produce an edgy, cracked effect. “Whether I’m on or off the court, style is important,” Serena said in a statement. “The White Shatter and Red Shatter lacquers allow me to add a high-fashion take to the elegant silver and sunset-colored polishes.” Serena’s new Glam Slam! lineup is $15 for two polishes, and lands in stores May 1st.

New shades in the Glam Slam! collection will be introduced to coincide with each of the four major tournaments, beginning with the Australian Open in January 2011, followed by launches in May 2011 for the French Open, June 2011 for Wimbledon and August 2011 for the US Open. As with all OPI Nail Lacquers, the Glam Slam! collection contains no DBP, Toluene, or Formaldehyde, and each includes OPI’s exclusive ProWide™ Brush for the ultimate in application.
