Watch The Stars Of 'Transformers: Age Of Exctinction' Play F--k, Marry, Kill With Robots

Kelsey Grammer confirms he likes 'wild bitches'.

What robot would you f--k?

That's really the central question of the very special game of "F--k, Marry, Kill" that MTV News' Josh Horowitz played with the stars of "Transformers: Age of Extinction" in a new "After Hours." The stars have to pick from Optimus Prime, Bumblebee, and baddie Galvatron.

Pretty much everybody ended up marrying Optimus, including Mark Wahlberg. "Optimus is my right-hand man," though he also said he "wouldn't have sex with any of them."

As Kelsey Grammer said, Optimus is a "model citizen," which would certainly make him a great husband.

A surprising number of stars ended up f--king the new bad guy, Galvatron, including Grammer, which makes sense, since he informed us that "I like wild bitches. That would be the wildest ride."

New castmember Nicola Peltz went for Optimus for the physical relationship too, and costar Jack Reynor agreed, though neither was too comfortable with the answer

"I'm sweating," Reynor said.

But what about poor Bumblebee? While Peltz would put the ring on his robotic finger, Ben McKee of Imagine Dragons, who wrote the end credits song for the movie, imagined (dragons) a darker fate for the fan favorite, prompting a big debate among the group.

"Don't kill Bumblebee!" exclaimed Daniel Platzman, while a displeased Dan Reynolds was unhappy Ben was "speaking on behalf of all of us."

So if Imagine Dragons breaks up, chances are it was over this game. But at least Bumblebee knows he's loved.

"Transformers: Age of Extinction" opens June 27.
