Nancy Sinatra shares her favorite photo of herself and her “dear friend” Elvis Presley as a tribute.

In honor of Elvis Presley’s 88th birthday, which would have been today, Nancy Sinatra recalled the fun times they had together.

The 82-year-old singer and performer celebrated the rock ‘n’ roll legend’s birthday on January 8 by tweeting a vintage image of her and an adolescent Presley laughing hysterically together. In 1977, Presley passed away at the age of 42.
