"Katy Perry and Robin Thicke have been named as next week&amp;#039;s X Factor guest performers. The musicians will each take to the stage during next Sunday&amp;#039;s (October 20) results show, host Dermot O&amp;#039;Leary announced at the end of tonight&amp;#039;s (October 13) first live results programme of the year.   Perry appears on the show ahead of the release of her new studio album Prism, which is out on October 21 in the UK and October 22 in the US. Thicke, meanwhile, visits the UK weeks after his track &amp;#039;Blurred Lines&amp;#039; was named the UK&amp;#039;s best selling single of 2013 so far. However, &amp;#039;Blurred Lines&amp;#039; has been banned by a number of student unions and Thicke has faced media criticism for the track&amp;#039;s lyrical content and the uncensored version of its music video, which features three topless models. O&amp;#039;Leary also confirmed during the first results show that next week&amp;#039;s X Factor theme will be &amp;#039;Love and Heartbreak&amp;#039;.
