Jennifer Stone shows off a Koh Gen Do product as she attends the DPA pre-Emmy Gift Lounge held at the Peninsula Hotel in Beverly Hills on Saturday afternoon (September 19).

The 16-year-old Emmy winner was feeling a bit frustrated later in the day. She tweeted, “You know those days where nothing goes right? That was today for me. Every thing that could go wrong did. I hate Murphy’s Law. I need to do something fun tonight, just escape for a bit.”

Be sure to tune into the season premiere of Phineas & Ferb — where Jennifer plays future daughter Amanda — @ 8PM ET/PT on Monday, September 21 on Disney XD.
