Celebrity polar bear Knut celebrates his 4th birthday with a party at Berlin Zoo
Fish and meat were served in the polar bear's snow-covered outdoor enclosure at the Berlin Zoo on Sunday, followed by a birthday cake shaped like the number 4.
As Knut gobbled up his cake, the spectators sang "Happy Birthday,"the German news agency DAPD reported.
The visitors also were given the rare opportunity to feed Knut, and he seemed to enjoy the bread, fruit and fish they brought for him.
Knut has been a star in Germany since he was hand-raised by zookeepers after his mother rejected him at birth.
