Battling for the top spot in the Dancing With the Stars
finals won't be Rumer Willis'
only tough fight this week.
The DWTS finalist
suffered a rib injury last week while training with partner Val Chmerkovskiy for their Judge’s Choice contemporary routine.
Their gorgeous "Swan Lake"-themed dance -- which the DWTS judges described as "beautiful," "a bit mad" and "brilliant dancing" and earned the couple a perfect score of 30 -- involved a ton of difficult lifts.
Unfortunately, all of the practice leading up to that intensive week nine routine badly strained Rumer's muscles, and her rib bones got extremely bruised.
Now, the partners are in overdrive rehearsing for two dances on Monday and a fusion dance on Tuesday, but it's very difficult for Rumer to practice. In an ET exclusive video, Val wants Rumer to see a doctor when the injury forces her to take a break during practice, but the 26-year-old actress insists, "I'm fine."
"I just need to catch my breath," she adds. "It's hard to take a deep breath, so I just need a second, and I'll be okay."
Rumer did say she felt good about the routine but wished "it wasn't so hard for me right now."
It's a bittersweet moment, especially when Rumer tears up explaining to Val, "I just don’t want to let you down." Her dancing partner gives her a kiss on the head and insists that she won't.
The DWTS Season 20 finals start on Monday on ABC. Riker Lynch and Noah Galloway are Rumer's big competition for the mirror ball trophy.
We hope Rumer feels better fast!
