Since rising to fame in recent years, she's earned a reputation as one of the more raw and edgy additions to the often-times saccharine pop music world.
And Tove Lo, 29, showed fans that boldness is another characteristic she can lay claim to, as she flashed her bare breasts while performing onstage on Sunday night.
As the Swedish beauty performed for the crowd at Boston's House of Blues, as part of the US leg of her Lady Wood tour, she nonchalantly hoisted up her black top and gave her braless bosom a moment in the spotlight while continuing to sing.
In the image, she is seen sipping from an ice-filled oversized cocktail glass at the popular live music venue, while wearing a baggy denim jacket.
'Boston I'm celebrating your awesomeness you were a f***king magical crowd... THANK YOU,' she captioned the shot.
This isn't the first time that the Talking Body hitmaker - named Ebba Tove Elsa Nilsson - has given fans a live view of her ample assets.
At Philadelphia's Jingle Ball in December, she took to the stage braless once again, wearing a mustard mesh top over black pasties, which covered her nipples.
The singer-songwriter rounded off her look with a pair of high-waisted pink leopard print hotpants.

The graduate of musical magnet school Rytmus Musikergymnasiet hit a career-high in 2014 in the US.
Her single Habits (Stay High) scored international success despite Lo initially self-released Habits in March 2013 and then reissuing it in December.
The song was remixed with California duo Hippie Sabotage and the remix hit the top 10 in a half-dozen countries in Europe and Oceania.
'The thing that I love about pop music is its simplicity and directness, ' she previously told Entertainment Weekly.
'For me, I love the mix of when it’s bittersweet in that sense. It can be a happy beat that you can dance to, but it still has to have a little bit of pain in there.
'Even if it’s a party song, if you’re having the best night of your life, it’s still going to end.
'You get kind of this desperation to not want something good to end. And that’s beautifully sad in a way.
'All that mixed together is what I want my songs to be. All of that at the same time. That’s kind of how I am—a roller coaster of emotions.'
