Among the female contestants on Tuesday's Ladies Night, model Joanna Krupa finished in first place based on the judges' scores. She was followed by Kelly Osbourne, who surprised many by coming in second. Proud parents Ozzy and Sharon Osbourne were in the audience.
This season boasted the largest "Dancing With the Stars" cast ever, with 16 celebrities vying for the Mirrorball Trophy.
The celebrities and partners practiced for a month at gyms and dance studios all around Los Angeles.
Osmond trained while doing his show in Las Vegas and Macy Gray practiced every day while on her European tour.
"Sometimes we would practice at the show at one, two in the morning," she told "GMA" special contributor Melissa Rycroft before the premiere.
"We practiced in hallways behind the stage, in conference rooms at the hotel," said her partner Jonathan Roberts.
Former Dallas Cowboy Michael Irvin was worried about what his appearance would do for his image.
"It took me years to build this tough man persona, and she wants me to lose it with a few hips and cha cha," Irvin said of partner Anna Demidova, who won the professional dance competition tryout and made her first appearance on the show this season.
Injuries are common during training for "Dancing With the Stars." Rycroft sustained one last season, and there were so many injuries that the show was forced to scale down on training time. This year, DeLay has already taken a hit, and he has the special shoes to prove it.
"They call it a prestress fracture," DeLay said of his injury. "They put me in these hiking boots. Aren't they cute?"
The day after he was announced as a contestant, DeLay told "Good Morning America" co-anchor Chris Cuomo that he "jumped at the chance" to appear on the show.
"I love dancing ... you've got to love dancing if you're from Texas," DeLay said. "Conservatives can have fun too. Conservatives can let their hair down ... and put on some dancing shoes."
