STEVE GUTTENBERG and MONICA SELES were in a great mood on Friday as they chatted up their upcoming debuts on "Dancing with the Stars."

"I never set a foot in a dance studio," Monica admits to ET. "The first two weeks were really rough. I was trying to come up with ways to get out of it -- fake an injury -- but the last few days, I am enjoying it and having a lot of fun."

When the competition begins on Monday night, Steve will be partnered with ANNA TREBUNSKAYA, and Monica will be taking to the floor with JONATHAN ROBERTS. Both couples will be doing the foxtrot for their first dance -- and they are looking forward to all the glamour and glitter that comes with a performance.

"As a tennis player, you are a tomboy," Monica points out. "I never got to go to my prom because I was playing in the French Open. This is my chance to dress up and be really girlie, girlie."

And Steve jokes, "I wear sequins and spandex in my normal life, so I have no problem with sequins and spandex. It is a little itchy on the underwear. You have to wear them on the outside."

"Dancing with the Stars" premieres on Monday, March 17 at 8 p.m. on ABC.
