PAUL MCCARTNEY AND NANCY SHEVELL- 12 YEARS

The legendary singer-songwriter Paul McCartney is a member of the most influential music group The Beatles. As one of the most successful composers and performers of all time, McCartney sold 25.5 million albums in the United States. He was included in the rock and Roll Hall of fame twice and won 18 Grammy Awards. The Rock and Roll Hall of Famer has a net worth of $1.2 billion and as much as he can enjoy a lavish lifestyle.

His wife Nancy Shevell also earns a fortune from her family business. After dating since 2007, McCartney officially married Shevell in 2011. Even though she is more than a decade younger than him, she has shown maturity in her love for him and their togetherness for 12 years proves it. McCartney must have a great degree of devotion for Shevell, as he wrote a song about her entitled My Valentine, from his 2012 album Kisses on the Bottom.
