Singer Brad Paisley, who has two sons with wife and actress Kimberly Williams-Paisley, says he wants to keep his sons in sync with reality.

"Not once have we been in a toy store and I've said, yeah, I'll get you that. We try to make them understand that nothing is free and they have to earn things," people.com quoted Brad as saying.

The singer, who released his new album "Moonshine in the Trunk" last month, learned his own lessons in 2013 after his song "Accidental racist", a duet with LL Cool J, caused a firestorm of controversy.

The criticism was "rough," he said.
