Carly Rae Jepsen attended the 17th Annual Arthur Ashe Kids' Day Stadium Show at the Billie Jean King National Tennis Center over the weekend. The Canadian singer posed with a gigantic tennis racket, wearing an appropriate tennis inspired plaid outfit.

Jepsen later changed into a cute white tennis frock to play a game.

The singer boasts the longest number-one run on the pop charts so this year with her summer ballad "Call Me Maybe."
