Though Randy Jackson Presents: America's Best Dance Crew is heading into its fourth season, there are still a few firsts for the show. For starters, the MTV hit is moving to a new day and time (Sunday, 9/8c) and will feature a crop of never-before-seen types of crews.

"Sometimes there are crews with a theme even though they're different, but this season, they're different all over the board," co-host Layla Kayleigh tells "We have our first real salsa, Latin crew. We have an all-African-American country group. They do line-dancing! We have our first all-gay male group with a transsexual in the group."

We Are Heroes has what it takes to become the show's first all-female winner, Kayleigh says, but she won't play favorites or make predictions. Fans, however, are in store for a great season with "really cool and different challenges."

Another thing that's going to be different? The size of Kayleigh's belly. The British personality and her boyfriend Steve Covino are expecting their first child in November — and the baby is already showing some moves of its own in utero.

"With the music [playing], the baby was going crazy! I swear my baby is going to be a B-girl or a B-boy because it's dancing already," Kayleigh says. "It's going to come out of me doing headspins. I just know it!"
