Things seem to be getting serious between Travis Barker and Kourtney Kardashian. In fact, fans are speculating that the 45-year-old drummer’s new tattoo is in honor of his 41-year-old girlfriend.

Barker posted a video of himself self-inking the new body art onto his right thigh. The message reads, “You’re so cool!” with a small heart next to it.

Shortly after posting the video, Kourtney commented on the post, “You’re so cool!”

Fans went wild, speculating in the comments that the message might have been written in Kourtney’s handwriting.

Barker later gave more insight into the meaning behind the tattoo. The message actually comes from the 1993 film, True Romance, the screenplay of which was written by Quentin Tarantino. The line comes from Patricia Arquette’s character in the film and the handwriting is her own after she writes it on a napkin in the film.

Barker shared more pictures of his ink along with still shots from the film, captioning the post with another line from the movie, “I like you, Clarence. Always have. Always will.”
