Beckham has started all three games since joining Milan
David Beckham scored his first goal for AC Milan in the Italian club's 4-1 Serie A victory against 10-man Bologna.
On loan from the Los Angeles Galaxy for three months, the England midfielder scored Milan's fourth goal, finishing off a slick move with a powerful shot.
Brazil's Kaka, who rejected a world record move to Manchester City last week, scored twice - a penalty and a shot from the edge of the box.
Milan's other goal was scored by veteran Dutchman Clarence Seedorf.

Milan got off to the worst possible start when Serie A top scorer Marco Di Vaio scored a ninth-minute penalty but Carlo Ancelotti's side soon drew level when Seedorf slid the ball home after Kaka's effort was parried.
Kaka then took control of the game, netting with a penalty and a superb left-foot shot, before Beckham wrapped up Milan's win.
"To score my first goal is great and I will keep this shirt, but the important thing is we won here," said Beckham, who is due to return to LA Galaxy on 9 March.
