Or tomato sauce.
Yep, the actor has a tattoo of a Heinz Tomato Ketchup bottle inked onto his calf.
The 27-year-old - who plays Jasper Cullen in the movie franchise - unveiled the bizarre tat to chat show queen (and HuffPost Celeb fave) Wendy Williams on her US show, and she looked about as impressed as us when she clapped eyes on it.
So, errrm, why?
"I love ketchup," he told her. "I got a lot of flack for it growing up from my family.
"My dad would always say ''Do you want a little hamburger with that ketchup?'' I was like ''Dad I hate that joke.'"
Not as much as we hate that tattoo.
Jackson isn't the first celeb to get a dodgy tattoo...
