Watch Jessie J and Jennifer Hudson Slay "Titanium"

Sorry, Pitch Perfect, but Jessie J and Jennifer Hudson's cover of "Titanium" is the be all, end all for David Guetta and Sia's track. Although it wasn't performed in a shower — instead, in Washington, D.C. at the HBO's Concert For Valor on Veteran's Day — it still induced the same amount of chills. At first glance, you think it's just Jessie J shutting it down with incredible vocals, but then J. Hud joins her and it's all too much. They take solo parts for the first few verses, then come together with amazing harmonies and soaring notes. Hey, Jessie and Jennifer, we're ready for a collaboration. You can even bring in a rapper like "Bang Bang" had Nicki Minaj if you want. You can also add Ariana Grande. Make it an all-girl super group, actually.

This concert was even more studded than just these two talented ladies. Other performers included Rihanna, Carrie Underwood, Eminem, Metallica, and Bruce Springsteen, and the event saluting veterans featured celebrity guests like Tom Hanks, Meryl Streep, John Oliver, and Will Smith. Hudson also sang the Star-Spangled Banner at the start of the show before a video message from Barack Obama played for the crowd.
