In a recent interview with Cipha Sounds & Paul Rosenberg on New York's Hot 97 station, when asked about the T-Pain allegations, Jay simply replied "I hope he had fun saying it."

In the brief snippet Jay also mentions choosing to not discuss Dame Dash and "haters" in general.

"When you hear people's gripe against me, it's always about what I didn't do for them. They never say what I did to them, it's always what I didn't do for them."
