JLS star Aston Merrygold has furiously hit out at a troll who racially abused his son on social media.

The offensive comment was posted on Merrygold’s two year-old son Grayson’s Instagram page and the singer wants any information on the private account behind it.

He said on social media last night: “I need to know who this person is ASAP because from when you think you can move like this and write s*** on my sons page.. you got the wrong one mate! So any information on @wickyaard need thrown my way now.”

The person behind the account seems keen to hide their identity as the profile picture is of Hollywood actor Woody Harrelson.

The image the troll posted on was of Grayson in front of his little brother Macauley’s, pram with the caption: "Big Bro Security... I also do other events such as birthdays, soft play and ice cream ques"

Merrygold and his fiancee Sarah Richards control their children’s pages. Grayson currently has 15,000 followers and Macauley, whose page is yet to be posted on, has 6,000.

An abundance of stars commented on Merrygold’s post saying they had reported the abuse.

Former Pussycat Doll Kimberley Wyatt, fellow JLS star Oritse Williams, Strictly Come Dancing’s Janette Manrara and singer Alexandra Burke all commented saying ‘reported’.

While singer Bluey Robinson wrote: “Scum.”

And artist Cimo Fränkel commented: “The hell is wrong with people, hiding like a lil b*+^h too”
