On Saturday, Beats by Dre posted this brief (1:18) YouTube video that arguably functions as much as an advertisement for Serena Williams' awesomeness (and killer body) as it does for the product: Powerbeats2 wireless in-ear headphones. (It's titled "Nothing Stops Serena." No kidding!) On Sunday, Serena Williams won her 18th Grand Slam title at the U.S. Open.
How was your weekend?
