Last time she hit the Dancing with the Stars ballroom, Karina Smirnoff walked away with a mirror-ball trophy.

This season, she's paired with pop singer Gavin DeGraw, as was announced Tuesday on Good Morning America, and will be blogging exclusively for PEOPLE.com with the inside scoop on what goes down on and off the parquet. (Past PEOPLE.com celebrity bloggers have included Kristin Cavallari and Chelsea Kane.)

"Season 14 is going to be very exciting and entertaining," Smirnoff, 34, tells PEOPLE. "We have so many diverse personalities and talents this season."
