300TH EPISODE

The show will feature music by The Wanted, who will perform their hit single, “Fill A Heart,” and Avril Lavigne will perform her new single, “Here’s to Never Growing Up.”

The 300th show celebration will also feature a spectacular opening number choreographed by Jason Gilkison with 22 pros, including returning favorites Chelsie Hightower, Dmitry Chaplin, Louis van Amstel and Anna Trebunskaya. In addition, the “AT&T Spotlight Performance” will return for its final installment of the season featuring Sophia Lucia, an incredible 10-year-old dancer who recently set the Guinness World Record for consecutive pirouettes.

And then one couple will be eliminated at the end of the night. At this point, signs are pointing to Ingo Rademacher and his pro partner Kym Johnson as the ousted couple, but you never know!
