Will.i.am admits to using parts of 'Rebound'

Quoted from The Sun UK (Via Pop Justice):

“Arty is a dope producer so I wrote this song to Rebound this last year.

“I got in touch with Arty and showed it to him... but something happened and hopefully we can resolve the issue.

“It’s sad that it’s turned into a fiasco but hopefully it’s resolved, because I’m a fan of those guys. I contacted them last year and we’re fixing it now.”

I hope so.
