NBC bosses have reportedly "warned" Tonight Show host Jimmy Fallon to cool it with the "out of control" drinking. The warning was given following a number of allegedly alcohol-inspired accidents, Page Six reported Tuesday.

There were fears that Fallon was out of control and something could happen while he's out drinking," a so-called "insider" told Page Six. "Things got so serious at one stage that execs feared that Jimmy was splitting up with his wife over his drinking, but they patched things up.

Fallon is also struggling with the fact that Tonight Show reportedly lost "key staff members" to CBS' Jimmy, a.k.a. James Corden. "Fallon is insanely jealous of Corden," a source told the Six team Tuesday. "There's been some upheaval and Jimmy hasn't handled it well. He's at the top of his game, but he's insecure.

I don't believe that he has a drinking problem. Love Fallon. Corden is funny too. There's enough room for both but crazy how Fallon lost key staff members to James' show. Carpool Karaoke winning an Emmy really must have done a number on Fallon's ego.
