The R&B songstress joined Chris Martin and his band for a performance of their hit "Princess In China" collaboration off the Mylo Xyloto album, as well as a new rendition of Ri's classic track "Umbrella."
There was no Hov verse, but it was a beautifully stripped-down version made even more beautiful with Chris on the keys.
Even though it was certainly a moment to remember for those in attendance, this won't be the last time RiRi and Coldplay link up with each other.
Rihanna and Coldplay are slated to perform at the Paralympic Games closing ceremony in London on September 9th.
