The toddler’s impressive performance comes after Laura and Matty J hinted at the gender of their unborn baby during an interview on Studio 10 on Wednesday.
When new host Tristan MacManus asked the couple if they knew the sex of their unborn bub, Matty said that he had an inkling a baby boy was on the way.
“I don't know if this is wishful thinking, but there's lots of kicks right now, so for me I'm like alright we have a little soccer player, rugby player,” Matty J began.
He added: “I would love a little boy.”
Matty J and Laura revealed the news of their second pregnancy in a sweet Instagram post, which featured a carousel of snaps of Laura's burgeoning bump.
"Marlie-Mae learning shocked face couldn’t have been timed any better.. WE’RE HAVING A BABY!" Matty J captioned one sweet snap, which shows his firstborn overcome with joy.
"Please brace yourself for twice the amount of dad jokes," the 33-year-old dad added.
