The Jonas Brothers and Sia took on Rihanna’s latest single “Diamonds” during separate concerts this past week.

While performing at Los Angeles’ Pantages Theater, the Jo Bros put their spin on the song sitting atop the Billboard Hot 100 chart. The brothers are on a reunion tour as they prepare to release their first album since 2009’s Lines, Vines and Trying Times. No word yet on when their fifth studio album will be released, though they did debut three new songs at their Radio City Music Hall concert in October, “First Time,” “Let’s Go” and ”Wedding Bells.”

They also performed a mash-up of their own “Tonight” and Fun.’s “We Are Young” during their first show in L.A. in three years. The Jo Bros return to the City of Angels Dec. 1 as part of Jingle Ball at the Nokia Theater. They head to South America in early 2013.

Sia, who co-wrote “Diamonds” – the first single off Rihanna’s seventh studio album, Unapologetic – shared her version while at the Norwegian-American Achievement Awards on Nov. 28.

The Australian singer-songwriter can also be heard on “Titanium” with David Guetta and Flo Rida’s “Wild Ones.” She penned “Blank Page” off Christina Aguilera’s Lotus as well.
