Eddie and Alex, 67, founded their namesake band in the 1970s. Eddie went on to become known as one of the greatest guitarists of all time, and the band was inducted into the Rock and Roll Hall of Fame in 2007. The band was most recently comprised of Eddie, Alex, Eddie's son Wolf and David Lee Roth.
Eddie's final Instagram post, dating back to May 8, is a birthday shoutout to Alex, which he captioned, "Happy Birthday Al!! Love Ya!!"(Alex, an ordained minister, officiated Eddie's 2009 wedding, when he tied the knot with Janie Liszewski.)
On Wednesday, Janie posted an emotional tribute to her late husband, sharing a peaceful photo of their feet as they relaxed on a sandy beach.
"My husband, my love, my Peep," she began the caption. "My heart and soul have been shattered into a million pieces. I never knew it was possible to cry so many tears or feel such incredible sadness."
