Pete Davidson

The 29-year-old comedian revealed on 'Ruthie's Table 4' podcast that he has one major no-no when it comes to women.

Pete won't romance any lady who is rude to waiters when dining out.

If someone flags a waiter down with an “excuse me”, then in his head he would be like, “Ok. Never. This is it.”

He added: “Like, just wait for the guy to walk by, and lightly [ask].”

Pete's exes include celebrity babes Kate Beckinsale, Ariana Grande, Kim Kardashian and Phoebe Dynevor.
