TMZ reports that the warrant, issued on Thursday, stems from a legal case with a Montana woman, who claims that Lohan is the father of her child.
Lohan is required to pay child support to Kristi Kauffman, who sued him in 2008 and eventually won an uncontested judgement when he failed to oppose the paternity claim.
Speaking to the website, Lohan insisted that he hadn't been aware of the warrant, but suspected that it had been issued after he was a day late making his second payment.
He also stated that the matter would be resolved once the money had been transferred.
