The show goes on at 'DWTS'

There's an old adage in showbiz that "the show must go on." That was the case Monday night at "Dancing with the Stars," as the celebrities and their pro partners took to the dance floor just hours after the devastating bombings at the Boston Marathon.

The victims of Boston were not forgotten during the show, as host Tom Bergeron, who spent much of his early broadcasting career in Boston, expressed his love to "everyone back home" in the city, while gymnast Aly Raisman, who was born in the suburb of Needham, dedicated her samba to Boston.

The nine remaining couples had to pick two other pros to perform simultaneously with them on Monday, meaning some popular pros who weren't picked to dance this season returned for at least one night. That included Maksim Chmerkovskiy, Anna Trebunskaya and Chelsie Hightower.

Disney star Zendaya earned the first 10s of the season, courtesy of a 29 for her Argentine tango. Country star Kellie Pickler continued to stay close behind Zendaya in the race for top celeb dancer of the season, garnering a 27 for her foxtrot.
