Machine Gun Kelly and his “Invincible” collaborator Ester Dean shared their support for one another during a candid conversation following their first performance together on “The Tonight Show with Jay Leno” last month.

“I’m so happy for you. You know how they go hard for somebody ’cause you know they deserve it?” said the “Drop It Low” singer, who’s readying her Interscope Records debut. “Go hard. This is this boy’s time, so go hard.”

MGK responded with his own form of flattery. “Her voice gives me an erection,” he said.

The Cleveland rapper, whose Bad Boy debut Lace Up is due later this year, was ecstatic to be on TV. “I called my aunt, who’s my only family member I have,” he recalled. “I said, ‘Yo, rub it in my dad’s face that his son’s gonna be on Jay Leno.'”
