7. Kristen Stewart and Taylor Lautner

For Twilight fans, the big debate was always Team Edward versus Team Jacob. For Kristen Stewart, though, it wasn’t really even a question. Kissing Lautner as Jacob felt strange because Bella had been with Edward for most of the story. Stewart said her intimate scenes with the wolfman felt weird and forced. It probably did not help that Stewart and Pattinson were dating at the time, which made the Edward scenes feel more natural.

8. Dane Cook and Kate Hudson

Dane Cook did not hold back when asked about his worst on-screen kiss. Without a moment of hesitation, his mind went to smooching Kate Hudson in My Best Friend’s Girl. According to Cook, Hudson’s breath smelled like a “feast of onions,” which is not ideal for an intimate moment. Who knows if that was an accident, a prank, or some sort of revenge, but if anything, it was quite unforgettable. Considering Cook’s comedy style at the time was not exactly known for being delicate, some people wondered if Hudson was simply messing with him.

9. Rupert Grint and Emma Watson

Hermione and Ron Weasley’s kiss in The Deathly Hallows: Part 2 was a huge moment for the entire fandom, but for Grint and Watson, it was nothing short of an awkward nightmare. Rupert said he had known Emma since they were kids, so kissing her felt very surreal. They grew up together with a sibling-like dynamic, which made the scene wildly uncomfortable. They did not rehearse it much, and Grint said one take was enough. After spending a decade together as childhood co-stars, romance was the last thing on their minds.
