PewDiePie's YouTube rival T-Series is closing in on 100 million subscribers.

YouTube sensation PewDiePie has been locked in a battle with Bollywood music channel T-Series over who can get the most subscribers.

It's a battle that spawned the 'Subscribe to PewDiePie' movement, as fans of the YouTube star attempted to keep him in first place.

But PewDiePie - who recently ended the 'Subscribe to PewDiePie' movement in a heartfelt video - has fallen far behind his rival in recent weeks.

At the time of writing, T-Series has amassed a staggering 97,716,187 subscribers.

That's compared to a hugely impressive 95,544,898 subscribers for PewDiePie.

According to tracking site Social Blade, T-Series is expected to reach 100 million subscribers in less than two weeks.

PewDiePie, on the other hand, isn't expected to reach the milestone for another 23 days.
