Berlin ? Michael Jackson rewarded fans outside his Berlin hotel with a brief appearance and a glimpse of his youngest child – dangling the toddler over a fourth-floor balcony.

The boy had what appeared to be a white cloth over his head as Jackson, briefly holding the child with one arm around the boy’s waist, displayed him out the window of the luxurious Adlon Hotel.

The child, wearing a baby blue jumper, was the reclusive singer’s third and youngest, Prince Michael II, said Antje Sigesmund, a spokeswoman for the Bambi entertainment award ceremony, which Jackson is attending in Berlin.

Several scenes of Jackson’s visit to the German capital – including the display of his son – were featured on national primetime German news, a sign of the King of Pop’s enduring popularity in Europe.

Jackson, wearing a bright red shirt, smiled and waved to the fans, at one point tossing a small white towel to the crowd below. The singer then went inside and retrieved the toddler, using one arm to hold the boy out over the iron rail of the hotel.

Little is known about Prince Michael II. People Magazine reported in August that he was 6 months old. The magazine, citing an anonymous friend, said the boy was not adopted and did not identify the mother.

The singer also has two children with ex-wife Debbie Rowe: a 5-year-old boy – also named Prince Michael – and a 4-year-old girl, Paris. The couple divorced in 1999.

In Berlin, Jackson was taking a break from a California courtroom where he testified last week in a $21 million lawsuit claiming he backed out of concerts. He will pick up a Bambi for life achievement Thursday.
