Marvel's Disney Plus series Loki has confirmed that Tom Hiddleston's character is bisexual. In the third episode set on the moon Lamentis-1 in the year 2077, Loki ( Tom Hiddleston) spends time with an alternate version of himself from another timeline. The variant is a female version of Loki who goes by the name of Sylvie as they become fugitives of the Time Variance Authority and become stranded on Lamentis-1 which imminently faces a nearby planet crashing into it. 

When a conversation between them drifts towards the subject of love, Sylvie asks Loki, “How about you? You’re a prince. Must’ve been would-be princesses. Or perhaps another prince.”

“A bit of both,” Loki responds. “I suspect the same as you. But nothing ever…”

“Real,” Sylvie says, finishing his sentence.

Series director Kate Herron highlighted the sexuality reveal of Loki in a tweet following the episode.
“From the moment I joined Loki it was very important to me, and my goal, to acknowledge Loki was bisexual,” she wrote. “It is a part of who he is and who I am too. I know this is a small step but I’m happy, and my heart is so full, to say that this is now canon in MCU.”
