From acting and singing to vlogging and activism, Troye Sivan has proven himself to be quite the Renaissance man.

He started his career in the late 2000s by performing on televised singing competitions, including StarSearch and Australian Idol, and even had a role in the 2009 film, X-Men Origins: Wolverine.

But Troye really started to gain people's attentions in the YouTube space with his own channel, which he started in 2012, leading to his now 4-plus million subscribers, which continues to grow rapidly each day.

In 2015, he formally made the move to music, releasing his debut album, Blue Neighbourhood and later headlined his own tour. And as of right now, he's dominating the club scene with his Martin Garrix collaboration, "There For You."

Troye has also been a big advocate for the LGBTQ community, and was awarded the Stephen F. Kolzak Award at the 28th GLAAD Media Awards earlier in 2017.

If you're a regular viewer of Troye Sivan's YouTube channel, then you have probably seen how he's grown from a wide-eyed teen to a young man. But for the rest of you who hopped onto the Troye train later, then see how he's grown up over the last few years in the photo gallery above.
