Rumer Willis To Sing, Val Chmerkovskiy To Play Violin For Dancing With The Stars Season 20 Freestyle

US Magazine is reporting some information about Rumer Willis and Val Chmerkovskiy’s freestyle. Read on for how Rumer will be singing. Val is going to play his violin….

A source tells Us that the duo will be doing their freestyle to a cover of Britney Spears’ 2003 hit single “Toxic” β€” performed by none other than Willis herself! The star, 26, who’s shown off her vocal prowess before in covers of Miley Cyrus’ “Wrecking Ball” and Adele’s “Rumor Has It,” has been “working on it for weeks,” the insider shares.

Chmerkovskiy is featured on the track, too β€” on violin! (As the DWTS pro, 29, revealed to Us in his “25 Things You Don’t Know About Me” last November, he’s a “classically trained violinist and played concertmaster violin with [his] youth orchestra in Carnegie Hall.”)

“Linda Perry produced the song, and it’s a really sexy, cool arrangement of Britney’s famous tune,” the source says. “They are super excited about it β€” it sounds absolutely amazing. Rumer’s thrilled to finally share it with the world!”
