Billie Eilish commanded attention as she "bared all" while making her way to the gym.
The 21-year-old singer wore an X-rated illusion T-shirt which featured a picture of bare breasts as she was spotted out and about in Los Angeles on Friday.
Billie also caused a stir as she put on a leggy display wearing a tiny pair of dark brown spandex shorts which she matched with white trainers.
The Happier Than Ever hitmaker tied her long dark hair back into a low ponytail which she wore under a black baseball cap.
She carried some essentials in her backpack and held onto a blue water bottle to keep her hydrated while she worked out.
The outing comes after Billie sparked concern amongst her fans as she posed for a series of 'strange snaps' during a racy bedroom photoshoot.
Billie sat with her legs pointed up to the ceiling and wore a little black dress, a pair of Gucci-branded tights and some jet-black heels.
In one snap, shared on Instagram, she looked into the camera lens while laying next to her bed, with her arms spread across the sheets.
"You’re looking right at me," Billie captioned the photos.
Some followers were concerned by the bizarre images, with one comparing her facial expressions to that of a "death stare".
"Are we bringing back MySpace angles?" asked one follower who couldn't quite believe the racy images.
Another added: "Something doesn’t feel right about these…" A third person said: "Give me a chance please."
Billie's comment section was also flooded with messages of support as another fan wrote: "Those ocean eyes get me every time."
"I dont think u understand how much i wanna be jesse rn," said one fan – referring to Billie's new musician beau Jesse Rutherford.
Another commented: "I love you so much billie eilish."
Someone else speculated that Billie could be about to drop some new music.
They wrote: "Remember when Billie posted a picture and the caption was… 'all the good girls go to hell'?
"No one knew what it meant because the song hadn’t come out yet and only days the song 'all the good girls go to hell' came out. I think we are going through the same ting again…"
