Demi Lovato is at the height of her career right now. Her latest record'Tell Me You Love Me' is her most critically acclaimed album to date and she is currently wowing fans and the public at large on a huge arena tour of the US with Kehlani and DJ Khaled.

To make things even more impressive, 'Sorry Not Sorry' just became her second ever Triple Platinum single in the US.

'WATCH DEMI'S BRILLIANT 'SORRY NOT SORRY' VIDEO HERE...'

LOVATICS ASSEMBLE. 'SORRY NOT SORRY' HAS OFFICIALLY BECOME DEMI'S BIGGEST SINGLE TO DATE.

The amazing lead single has been popular ever since it was released last July and now it has sold over three million chart copies in the US. In doing so, it joins 'Give Your Heart A Break' as Demi's only hits to date to reach the massive music milestone.

Considering how popular it still is, we reckon that 'Sorry Not Sorry' could go on to become 4x Platinum in the US.

As it stands, 'Sorry Not Sorry' is Demi's highest charting single in the US ever. Peaking at Number 6 it out-charts Demi's other incredible Top 10 singles: 'This Is Me' (9), 'Skyscraper' (10) and 'Heart Attack' (10). Not only that but it's a UK Top 10 hit too.

And, even more impressively, it is Demi's most streamed single yet with 424 million streams on Spotify alone.

We have no doubt that it will surpass the 500 million stream mark on the popular service before 2018 ends.

With plenty more potential singles on' Tell Me You Love Me', Demi may have another huge hit on her hands.

'Daddy Issues', 'Ruin the Friendship' and 'Dirty Sexy Love' could all be assuccessful as 'Sorry Not Sorry'.
