‘Oh nice!’ she exclaimed at one point to reward Arnold’s efforts on the black grand piano.

The mother-son duo were an adorable partnership – even matching the colour of their attire in a pair of grey sweatshirts.

The two were also joined on the piano stool by Arnold’s cuddly toy as the young boy enjoyed some quality time with his famous mother.

Earlier this month, his father Ed revealed he and Tiffiny were keen to expand their brood, saying that having another baby is ‘definitely’ in the couple’s future. 

The 39-year-old comedian shared his baby plans in an interview with TV Week, while admitting Arnold didn’t actually find him funny. 

Have You Been Paying Attention? star Ed told the publication he and his fitness trainer wife would ‘love’ to become parents again. 

Not such a funny guy: In his interview with TV Week, Ed confessed that little Arnold is his harshest critic and doesn’t actually find him funny despite his comedic genius

Doting parents: The couple, who married back in 2014, are already parents to Arnold, who Tiffiny is often sharing sweet photos of on social media

‘It’s definitely in our future, if we’re lucky enough,’ he said. 

The couple married back in 2014 and welcomed Arnold three years later. 

But while he may be loving fatherhood, Ed suggested his little boy is his harshest critic, as Arnold doesn’t actually find his comedic father that funny. 

‘It’s very frustrating, I do all this material, pull faces… nothing,’ Ed claimed. 

He then went on to reveal that he did get Arnold to laugh on one occasion, but it was more over his misfortune as he accidentally tripped over while going to feed him.
