Their love story was tragically cut short in 1998 when Eastman died of breast cancer.

McCartney and Mills would go on to separate in 2006, eventually finalizing their divorce in 2008.

During this stressful time, McCartney met his future third wife, Nancy Shevell.

The pair started dating in 2007, and would eventually get married in 2011.

But who exactly is Shevell, and how did she and McCartney initially meet?

Shevell was married to lawyer Bruce Blakeman at the time, with whom she shares a son named Arlen.

“Nancy is like a second child to me,” Walters toldThe Observer.

“Her two aunts died of cancer.

She’s struggled in her life.”

“She doesn’t want anything to do with publicity.

She’s turned down a piece in Vogue.

She doesn’t want anything to do with music.”

However, Shevell did give a short comment to The Observer in 2011, explaining why.

“It’s just not that intriguing,” she said as she was leaving an MTA meeting.

“Not like his last marriage, which wasreallyintriguing.

I’m over 50.

I haven’t been social and I have a small group of girlfriends.

There really isn’t much to talk about.”

Despite this, McCartney hasn’t been shy about sharing his love for his wife on social media.

“Congratulations Nancy on our ninth Wedding Anniversary.

Thanks to nine beautiful years of marriage,” he wrote (viaInstagram).
