Los Angeles: R&B star Rihanna has released her new single "Work" from her hotly-anticipated album Anti.
The 27-year-old singer uploaded the link to her new song -featuring Drake - alongside the cover photo, which sees the star posing topless on her Twitter page.
"FIRST SINGLE #WORK ft. @champagnepapi from #ANTI out now," she captioned the image.
The cover shows the singer completely topless, with her arms over her chest to protect her modesty.
Rihanna smiles for the snap, with her hands over her eyes so just her mouth can be seen. Her black hair is in quirky twists and the name of the track is written down the side of the cover.
The single marks the second time Rihanna and Drake have collaborated, after teaming up on "What's My Name", from her 2010 album Loud.
