Rumor has it Dancing With the Stars already has a frontrunner!

At the end of the season 20 premiere, all eyes were on Rumer Willis as she debuted in a big way on the ABC reality hit, landing the top score of the night and rave reviews from the judges with her professional partner Valentin Chmerkovskiy. Cheering on Rumer from the audience? Her parents, friendly exes Bruce Willis and Demi Moore, as well as sisters Tallulah Willis and Scout Willis, who were all visibly moved by Rumer's incredible performance.

And though both mom and dad have some dance experience, Rumer tells E! News she didn't want to turn to her parents for any advice.

"To be honest, I sometimes just like to surprise them and I like to be able to not necessarily ask them anything and just let them come and see me do my thing," she says. "They were so unbelievable supportive, which was incredible."

And while Rumer is suffering from some "mental soreness," her partner Val was quick to gush about the actress and singer's work ethic. "She's such a trooper. I'm such a tough coach sometimes, she's just awesome. I want the best for her."

Which includes the best costumes. "This is just the beginning. This was us still just holding back and being modest," Val says of their opening night look, which included a beaded dress with a plunging neckline for Rumer. "We're going to have some sparkles!"

To hear more from Rumer and Val about their epic DWTS debut and what fans can expect to see from their next dance, watch the rest of our interview with the couple to beat!

DWTS airs Mondays at 8 p.m. on ABC.
