Piers Morgan marks

In view of his 1.3 million Instagram followers, Piers was pictured in bed with Susanna.

The ITV presenter can be seen reading an “I Love Me” book as his co-star looked at him in shock.

He wrote: “Happy 50th Birthday to my fabulous, long-suffering TV wife @susannareid100 who when first told I’d been hired to be her co-host 5years ago responded, ‘Are you ****ing joking????!’ Time’s been a great healer…”

Fans flocked to comment on the post, as many people gushed over Susanna’s youthful appearance.

Earlier this year, Susanna spoke candidly about reaching the major milestone and said it’s not a cut-off point.

“I definitely feel more comfortable with myself,” Susanna explained.

Susanna noted 20 years ago she remembers she would look in the mirror and question why she didn’t look like her then-idol, Patsy Kensit.

“I’ve got to an age where this is who I am and I’m happy with that,” she added to The Sun.

Meanwhile, the GMB presenter had cause to celebrate after she was awarded the “world’s best bum” beating reality star Kim Kardashian to the title.

The TV host also beat co-star Laura Tobin to reach the top spot in new research, which takes mathematical proportions into account.

“I feel like that was definitely a study done pre-lockdown,” Susanna replied. “I’m not complaining. It feels fantastic!”

Elsewhere, the GMB presenter’s ITV documentary Death Row’s Women, which saw her come face to face with child murderer Darlie Routier in a Texas prison, airs tonight.

Death Row’s Women With Susanna Reid airs on ITV at 9pm.
