The controversial footballer posted a series of messages today on Twitter in response to an article from the publication suggesting he is worried about having gained weight since the end of the football season.
"What a load of balderdash in today's Daily Star," Barton said. "Not my style but because u have quoted me and it's complete lies, I'll have to sue. Thanks.
"Unless of course the co-editor comes out wearing a clown suit and public accepts the fact she's a BAD liar."
Barton added: "The fact they had they audacity to call me a 'plonker' as well. Quite funny how bad of a firm of liars they are.
"How do they think that absolute lies in this day and age, are going to be accepted. Are they that stupid? appears they are.
"Their lie is not to call me a 'plonker' plonkers, that's just an opinion the real lies are in the rest of the article and its made up quotes."
