Leno has slammed Letterman…in primetime.

On The Jay Leno Show Friday, the former Tonight Show host couldn’t help cracking a joke about the $2 million blackmail bombshell against one-time rival David Letterman.

“If you came here tonight for sex with a talk show host, you’ve got the wrong studio,” Leno said, starting his monologue.

“What is going on? First Conan hits his head, and then somebody tried to extort money from Letterman,” he asked. “I’m so glad I’m out of late night,” Leno quipped. “I’m happy to say that I’ve never had a sexual relationship with any of my staff members.”

Did Leno go too far?
