X Factor judges Demi Lovato and Simon Cowell have always messed with each other. Cowell usually reminds Demi what a “brat” she is, while Demi reminds Simon how “old” he is.

Demi Lovato, who joined Cowell as a returning judge on The X Factor for season three, took to Twitter to mess with Cowell a little more. The 20-year-old “ Give Your Heart a Break” singer found an “ancient” picture of Cowell and shared it with her more than 14 million Twitter followers.

“Well, well. Look at this ancient pic I found!! Same t-shirt, same middle part.. Recognize this @SimonCowell??” she wrote, sharing a photo of young Simon, who is wearing a tight white V-neck t-shirt. The wardrobe choice has pretty much become his signature.

Lovato isn’t one to hold her tongue, especially when it comes to Simon. According to the UK’s Daily Mail, in a recent interview with Radio One she didn’t hesitate to make jokes about him. She said he smells “like money, cigarettes and mints,” and he’s always late. She says she returned to the judging table “strictly to tell him off.”

The X Factor with new judges Paulina Rubio and Kelly Rowland returns this fall, and chances are Demi and Simon will pick up right where they left off when it comes to bickering at the judges table.
