We knew they were both going to be at the event, they've both been pumping it up for awhile. I wondered if they were going to sing together or maybe Blake would do one his famous Voice covers. However, I never thought that Usher would be doing a Blake cover!!! He nailed it too!

The United Way brought out some big names for their 90th anniversary celebration, including former First Lady Laura Bush and her daughter Jenna Bush Hager. First Lady Laura Bush and her husband former President George W Bush were honorary co-chairs for the event.

Not to be outdone, the two also performed Blake's "Home" together ... which is something they've done before.
