In the voice note, Grado’s father can be heard speaking very slowly, seemingly worried that if he didn’t do so his message would not be received.
He reads the message tentatively and clearly with some users suggesting he believed the recording would transferred into a text message.
He can be heard saying: “I have got you a steak pie.”
He posted a video of the note to Twitter yesterday, writing: “My faithers first WhatsApp voice note.”
The post has received over 220,000 views with more than 9,500 likes, 400 retweets and 200 comments.
The Two Doors Down star’s fans found the post hilarious, replying in their droves.

Grado and his girlfriend welcomed their first child to the world early in November this year.
The entertainer and his girlfriend of three years took to social media earlier this year to announce they were expecting a baby as they shared a photo of a scan.
