Two of the world's biggest pop females are set to team up, with US pop brat Ke$ha teasing a new duet with Rihanna.
The star has tweeted a number of images suggesting a collaboration with the 'We Found Love' megastar as she gears up for the release of new single 'Die Young' and follow up album to her 2010 hit, Animal.
The 'We R Who We R' chart topper shared a photo of a waffle-house waitress holding a piece of paper with an 'R' on it with the cryptic message 'what's it all mean?'
She also shared the artwork for her new single with the words 'getting closer. get hyped. eternal boners'.
Check out Ke$ha's waffle house waitress picture below.
Yesterday a teaser video for her 'Die Young' single premiered online, showing the star singing the track on the Tokyo underground - much to the surprise of her fellow commuters. Watch the video below. 'Die Young' is due for release in late September.
