The Chase viewers had to do a double take after finding out a youthful looking contestant’s real age.

The latest episode of the ITV show saw Amit, Helen, Pete and Lexi tackle the cash builder before going head to head with Mark "The Beast" Labbett.

But while the rounds were played out, viewers were gobsmacked when they found out Helen’s age.

Helen began by telling host Bradley Walsh that she had “seven and a bit grandchildren” and lives at the bottom of her daughter’s garden.

Bradders cracked up with laughter before saying: “You sound like a Hobbit.”

To which Helen replied: “I am, I live in a little cottage at the bottom of the garden.”

When asked what she wanted to do if she won any money, Helen then revealed her big number.

She began: “I had a list of 70 challenges I wanted to do for being 70…”

Shocked Bradley cut in: “You’re not 70?”

“I am,” she replied, before gushing: “Brad, I love you!”

He went on to tell Helen she looked “really well” for such an age.

“Ooh it was really worth coming for that, I don’t care about the money,” quipped Helen.

Viewers were equally shocked by the revelation, with some saying she looks as much as 25 years younger.

One tweeted: “You have to admit though, she looks incredible for 70. She looks in her mid 40s.”

A second said: “Did I hear right aged 70?”

A third posted: “Helen doesn't look 70 fact.”

“Helen looks amazing for 70,” another agreed.

“Helen does look good for 70 though,” said another.

And: “She looks great. Remember, she’s 70 and lives in a shed.”

The Chase airs weekdays from 5pm on ITV.
