You have to admit, celebrity feuds are incredibly entertaining. But, with the invention of social media and social networking sites, feuds between celebrities has become more and more frequent, fun, funny and sometimes downright disrespectful. Think about it, the feud between Vin Diesel and Dwayne Johnson probably help added a new level of media attention to the multi-million-dollar movie. Also, the feud between Katy Perry and Taylor Swift is still making headlines year since the rumors first surfaced.

Now a new feud is beginning to brew over on social media. Over the weekend David Spade ran into Internet star Danielle Bregoli, also known as the “Cash Me Outside” girl. After posing with the teenager at a Los Angeles eatery, Spade posted the picture on Instagram with a joke, saying, “Unfortunately, she stopped being famous 5 minutes before this was taken.”

Bregoli, apparently too young to remember any movie David Spade was ever in, was clearly unamused in the photo and fired back “No lie, I thought dis guy was the waiter.”

At the end of the day, no one comes out a winner in a celebrity feud. In fact, Spade picking on a teenager is a little scary. That said, Bregoli probably has a bigger acting career than Spade.
