The couple met in high school, at a party after the senior prom, and they married at the National Cathedral in Washington on May 19, 1970. They have four children together.
In 2000, Tipper Gore told the Washington Post that her first impression was "Oh, boy! He's good looking."
After high school, Tipper followed Gore to Boston, where he attended Harvard University. Gore once suggested their relationship inspired the 1970s novel and film "Love Story." But author Erich Segal later said the character was mostly based on Gore's college roommate, actor Tommy Lee Jones.
The couple later found interests that led them into public service. For Al Gore it was a life in politics, representing Tennessee in the Senate. Tipper Gore became a staunch advocate for printing parental advisories on music containing explicit lyrics.
She also spoke openly about a life-long struggle with depression.
By all accounts the couple was very much in love for a very long time, regularly sending each other love notes and expressing their affection for each other openly.
In 2000, at the height of Al Gore's presidential campaign he and Tipper exchanged titillating emails during preparation for a debate, which she shared with The Associated Press.
"I love you. How are you doing? I'm in the middle of debate prep. Paul [Begala] is talking. They're wondering what I'm doing," Gore wrote his wife from his Blackberry.
"Oh, I know what I'd like to be doing with you right now," replied his wife. Adding something she described as "a little lascivious."
"I'm losing my concentration now. We have to stop," quipped Al.
Gore did not ask Bill Clinton to campaign with him, despite the recommendations of his advisors, who believed the popular president would be a boon in Gore's run.
Al Gore refused, according to Coelho, because he was deeply hurt and offended at the casualness with which Clinton treated his marriage.
"One of the reason he didn't use Clinton was because of Clinton's dalliances. He was upset about it -- sincerely upset about it," Coelho said.
"Partners, they were true life partners. And it was something I witnessed. I saw it many different ways. I'm just very surprised," he said.
