New research reveals that adorable pandas are the most romantic beasts on earth.
Scientists from the U.S. and China have spent years studying the famed bears' mating rituals, and they have discovered that the cuddly black and white animals are hopeless romantics.
Sex between promiscuous pandas is best when their partners sing them - what scientists have deduced to be - a love song beforehand, whispered into their ears during intercourse.
Sweet songs are reportedly "crucial for achieving behavioural synchrony and signalling intention to mate."
But the songs could provide help for the endangered animals with the songs leading to baby pandas.
"This could also provide a valuable tool for breeding programs," the study found.
