Milan vice-president Adriano Galliani claimed last week an announcement was imminent - and it has been confirmed on the club's official website this evening.
Beckham moved to the San Siro during Major League Soccer's off-season last January, initially on a three-month loan deal, but impressed so much his stay was extended until the end of the Serie A campaign.
Milan have announced a six-month deal on this occasion, meaning Beckham will remain in Italy up until the 2010 World Cup finals in South Africa.
"We are very happy to see again David Beckham with the Rossoneri jersey after the splendid experience of last season," AC Milan vice-president Adriano Galliani said on the club's official website.
"We are certain that this time in Europe will help the player take part in the next World Cup and to continue after his career in Los Angeles Galaxy, to whom we thank for their time.''
