Nancy Grace Talks 'Dancing With The Stars' Rehearsals, Costume On 'Good Morning America' (VIDEO)

Nancy Grace dished about her dancing skills and her costume for "Dancing With the Stars" on Friday's "Good Morning America."

The HLN host and her dancing partner Tristan MacManus appeared on the show and agreed that rehearsals have been going well -- albeit teasing each other in their accounts.

Grace joked, "According to me, it's going great, but I've got this Irish dance partner and I hear this ringing in my ears every night, 'No, no, no!'"

Grace, who has lost ten pounds preparing for the dancing competition, admitted that juggling the day-long rehearsals with parenting and hosting her show at night has been "very, very difficult." She said that the hardest part was being away from her children.

Monday night's premiere will test whether the work has paid off. Grace divulged that the pair will be salsa dancing, and gave one key detail about her costume. "Tons and tons of sequins," she said. "Let me say that these outfits are very revealing."

Viewers also got a glimpse at the dynamic between the duo. When "GMA" co-host Josh Elliott asked McManus, who is from Ireland, if he had heard about his tough-talking partner abroad, he said that he hadn't.

"That’s not true," Grace joked. "I looked at his computer. There were tons of Google, Yahoo searches of Nancy Grace, Nancy Grace. So sad. Obsessed. Fixated."
