JB has said the band are definitely up for joining the line-up.
On Monday it was reported that Mitch, Amy Winehouse's dad, was planning a memorial concert for Amy after tributes flooded in from musicians across the globe.
And JB from JLS has confirmed the 'She Makes Me Wanna' singers would love to be involved.
"If there is a memorial concert for her of course we would be honoured to take part," JB spilled.
"The same as with Michael Jackson.
"I'll have to get our management to talk to organisers of that show in Wales."
An MJ tribute concert is taking place in Cardiff in October but there's no word yet on if or when an Amy Winehouse show will take place.
