Over the weekend, the former TOWIE star and the actress were overjoyed after they paid a visit to Michelle's cousin Katie Fearnehough, who had welcomed a new baby boy.
After sharing some sweet Instagram photos with the couple looking rather "broody," Mark's father, Mark Wright Sr, was quick ask his son and daughter-in-law to make him a grandfather soon.
"Lovely baby and it's about time you made me a grandad and your mum a grandma," he wrote, while Carol commented: "Oh beautiful little boy x x suits you."

Sitting on a sofa with baby Brody sweetly sleeping on his chest, Mark confessed his love for the little tot, writing: "The day I met Brody. New member to the clan. Gorgeous little boy. @katiefearnehoughx & Tony he is beautiful!! Love him already."
Over the years, both Mark and Michelle - who tied the knot back in 2015 - have constantly fielded questions about when they will start a family, with the actress previously admitting she feels frustrated by the constant speculation.

In an interview with Cosmopolitan, she said: "A few years ago it didn't bother me and I answered the question, but now I think, 'I don't need to answer that because nobody knows what goes on behind closed doors.'
"I remember when I finished Our Girl, people were like, 'Is it because you’re going off to have a baby?'" She continued: "I know for a fact if Mark finished a job, nobody would ask him if he was going to have a baby. It's not fair. It does make me feel frustrated."
