The Titanic star was given two pot-bellied pigs, called Mabel and Socks, for her 40th birthday last month (Oct15), and she instantly fell in love with the adorable animals.

However, her neighbours in West Sussex, England might be less enthralled with the playful porkers as they are frequently wandering away from home and investigating nearby properties.

Kate tells U.K. talk show host Graham Norton, "I got two pigs, called Mabel and Socks. They are a little bit of a nightmare as they keep escaping. The other day they were found up the lane trying to break into the local cafe... (I) play with them, they are pets. They are seven months old and you call for them and they come - it's really very sweet."
