Olivia's 'Physical' voted sexiest song of all time

It emerged on the top of a list compiled by Billboard.Com based on the performance of songs about sex on America's Billboard Hot 100 chart.

'Physical' saw off competition from Rod Stewart's 'Tonight's The Night' in the race to the top spot, while Boyz II Men's 'I'll Make Love To You' came in third.

Marvin Gaye's 'Let's Get It On' and the late Donna Summer's 'Hot Stuff' also made the top 10.

Stewart was the only artist with more than one entry - his 'Do Ya Think I'm Sexy' was at number 10.
