The race car sponsored by Justin Timberlake's William Rast clothing line won the Indy 500 in Indianapolis, Indiana on Sunday.
"What a Memorial Day weekend!" the singer-actor tweeted. "The William Rast car just won the Indy 500!"
The car, driven by racing veteran Dan Wheldon, beat out 32 other drivers for the coveted Borg-Warner Trophy.
Timberlake, 30, founded William Rast with his childhood best friend Trace Ayala in 2006. The line is best known for its premium jeans, but also produces other clothing items such as jackets and tops. The company's name comes from a combination of Timberlake and Ayala's grandfather's names.
