“Bloom” singer Troye Sivan has stunned Gay Twitter… by revealing that he is not a bottom.

The Australian pop singer is no stranger to getting plenty of attention on social media, forging his pop career out of an obsessive following on YouTube.

But the star came face-to-face with some of the sauciest messages sent to him by fans in a video with BuzzFeed.

In the clip, the “Bloom” singer is nearly lost for words as he reads out gay sex fantasies from fans.

One tweet reads: “Good morning America I am awake and I want Troye Sivan to spit on me.”

Sivan responded: “I was about to say, I’m into that, but like, whoa. Whoa!”

A second user wrote: “Troye Sivan more like lick honey off of me while singing Mary had a little lamb.”

The singer responded: “That’s like the most specific sexual fantasy I have ever heard in my entire life.”

There was a major plot twist when the singer read a thirsty fan tweet that reads: “I wish Troye Sivan could murder my ass but he’s already a bottom.”

Sivan responded: “Not true, but whatever!”

Another joked: “troye sivan isn’t a bottom? wow WOW all of u fanfiction writers get to work, i KNOW y’all got work to do.”

Troye Sivan track “Bloom” is about bottoming during gay sex

Fans noted that one of the singer’s best known tracks, his single “Bloom,” is all about bottoming and gay sex.

After the song’s release in May this year, he tweeted the hashtag “#BopsBoutBottoming,” while setting his Instagram location on a post about the song to “Bikini Bottom.”

The lyrics in “Bloom” referring to gay sex include: “Take a trip into my garden, I’ve got so much to show ya.”

The song’s pre-chorus continues: ”I need you to tell me right before it goes down / Hold my hand if I get scared now / Take a second, baby, slow it down.”

The pop star came out as gay in two YouTube videos back in 2013.

“This is not something I’m ashamed of, and this is not something anyone should have to be ashamed of,” he said.

“I know this could change everything for me, but it shouldn’t have to, and this is why I’m making this video.”
