A Calgary couple can now lay claim to a Guinness World Record after their pot-bellied swine was confirmed as the oldest pig ever. 

Ernestine, a Vietnamese pot-bellied pig already sporting a few grey hairs, celebrated her 23rd birthday in July.

Her owner says she's shy, loves to cuddle and doesn't eat too much.

The 70-pound swine is the beloved household pet of Calgarians Jude and Dan King.

"Dan just Googled it one day and found out that the oldest pig on the Guinness World Records was actually about seven months younger than Ernestine," said Jude King. "So we started preparing our documentation cause we thought well she deserves to get in there. She's older." 

Jude King says they're expecting a certificate in the mail from Guinness next week.

"Well she knows she's a big deal," she laughed. "She gets a few extra grapes and raspberries, you know, just cause she's old."

King says it took three months to get the paperwork together to prove Ernestine's age.

She is six months older than the previous record holder. The life expectancy for the average pot-bellied pig is 15.
