Visitors who want to see the Royal Academy of Arts' next exhibition will have to squeeze past two naked people in order to get to it

The exhibition, which opens this weekend, is curated by controversial artist Marina Abramović - who previously invited visitors to slash her throat and scooped fake blood from a naked woman's body with Lady Gaga.

The 76-year-old's previous work includes 'Rhythm 0' where she placed 72 objects including a bullet, gun, scalpel and metal bar on a table and invited visitors to interact with her however they wished - resulting in a loaded gun being held to her head.

In 2010 Abramović appeared at New York's Museum Of Modern Art with The Artist Is Present, in which she sat in silence for three months with visitors invited to gaze into her eyes.
