Instagram Beef: Anthony Pettis, Rafael dos Anjos and cereal boxes

Anthony Pettis recently offered to help Donald Cerrone to train for his title bout, because he apparently 'hates that motherf****r' Rafael Dos Anjos. While both men have other bouts lined up, former title opponents in Showtime and RDA are still continuing to trade barbs online, most recently exchanging instagram posts about cereals.

Dos Anjos started it with this post that came with the following caption: "Hey kids, whatch out for expired boxes ||--->>>Aí criançada, cuidado com as caixas vencidas #RDA #AndStill #ufc"

Showtime responded with a cereal box of his own: "Not everyone's face is made for a cereal box. But jus in time for Halloween, best served with juice... I'll get my strap back for sure but I'm focused on who's next. Slip up won't ever happen again!!!! Wasn't gonna address it but he had to post."

Before the two can even think of competing once again, they still have other opponents in front of them. Pettis is set to take on Eddie Alvarez on January 17th, while Dos Anjos will be defending his title against Cowboy on December 19.
