If you’re not familiar with the term “showmance” or “PRomance,” it’s when two celebrities who are tied to a project start dating for the duration of the project and then break up once it’s over. It does the job of generating buzz for the project and feeding crumbs to rabid fans. Here are some of my personal fave fake PR relationships — confirmed and alleged!!! — and press tour flirtationships throughout the years:1. Pamela Anderson and Liam Neeson for The Naked Gun in 2025:Two people in a playful moment on a talk show set, with one gently touching the other's chin. Shelves with books and decor in the background

Earlier this summer, Pamela Anderson and Liam Needson allegedly faked a relationship to help generate buzz for their comedy, The Naked Gun. Both claim that their relationship was real, but the pair quietly/conveniently ended things after the press tour.

During the press run for this unexpected rom-com hit, Sydney Sweeney and Glen Powell sparked romance rumors, even though they were both in committed relationships at the time. Months after the buzz of the film died down, they both came out and said there was nothing romantic between them, just a genuine friendship. Sweeney was in a relationship with Jonathan Davino from 2018 to 2025, and Powell was in a relationship with model Gigi Paris from 2020 to 2023.

Dianna Agron and Alex Pettyfer met on the set of I Am Number Four and ended things  days after the film’s premiere in 2011. They didn’t end on good terms — Agron moved out of their shared home and into a hotel under an alias in order to avoid Pettyfer. Since then, Agron has been linked to Sebastian Stan, Chris Evans, and was married to former Mumford & Sons bandmember Winston Marshall from 2016 to 2020; Pettyfer was married to model Toni Garn from 2020 to 2023.

Even though at the time, Twihards rejoiced at the off-screen/IRL coupling of Kristen Stewart and Robert Pattinson, in recent years, fans and critics believe that their relationship may have been all for show. The two of them were linked between 2009 and 2013 (with a brief break in 2012 during the scandal between Stewart and her Snow White director Rupert Sanders) before going their separate ways (coincidentally after the final Twilight film wrapped up its press tour). Since then, Stewart has been with her now-wife, screenwriter Dylan Meyer, since 2019, and Pattinson was in a relationship with musician FKA Twigs from 2014 to 2017 and has been with model/singer Suki Waterhouse since 2018.
