Justin Timberlake returned to Saturday Night Live once again over the weekend, portraying Grammy winner Bon Iver in a skit about Jay-Z and Beyonce's daughter Blue Ivy. In the skit, a series of musicians visit the musical couple (played by Jay Pharaoh and host Maya Rudolph) to see their child. When the mellow Justin Vernon of Bon Iver visits, he lulls the baby to sleep with a parody of his Grammy-nominated song "Holocene."

Davis died at the Enloe Medical Center in Chico, CA, after receiving a month-long treatment for liver disease, according to Rolling Stone.
