Kate Middleton

Pregnant celebrities - Kate Middleton and Prince William top a couples poll as Britian's Duke and Duchess of Cambridge were voted the world's most perfect couple.

Prince William and Duchess Catherine - who are currently expecting their first child together - topped a poll by UK TV network Watch, to find the celebrity pair British couples aspire to be like in 2013.

William and Catherine - who was known as Kate Middleton until her wedding in April 2011 - beat good friends David and Victoria Beckham into second place while Brad Pitt and Angelina Jolie came third, with Beyonce and Jay-Z in fourth.

Despite recently getting engaged, people questioned in the poll thought Katie Price and Kieran Hayler will be the first celebrity couple to split in 2013, closely followed by parents-to-be Kim Kardashian and Kanye West.

The survey - which was carried out from Monday 14 to Tuesday 15 January with 1,000 participants by market researchers Vision Critical - was commissioned by Watch to mark the launch of 'Beauty and the Beast' on Wednesday 16 January at 9pm.
