The Take That star was honoured with an entertainment award at the prestigious ceremony held in Berlin, Germany.
Robbie, who is preparing to release his new album, Swings Both Ways next week, also performed his new single, 'Go Gentle', which is dedicated to his daughter Teddy.
Robbie, who looked smart in a black tailored suit, was in good spirits as he kissed the gold bambi. Taking to Twitter, he simply said: "Thank you Bambi. RW x."
Speaking about his win, the Bambi jury said: "Robbie Williams is the most successful European pop star of our time – and certainly the coolest one, too. Like few others, the artist from Great Britain knows how to take him and his status as superstar with a smile.
"His often self- mocking lyrics, videos and interviews express a strong personality, which isn't influenced by the enormous commercial pressure of the music business. With his album Swings Both Ways, Robbie Williams shows once more that he is a natural born entertainer who expertly masters several genres."
The star-studded ceremony was also attended by Miley Cyrus and Victoria Beckham, who was honoured with a fashion award.
Swings Both Ways is due for release on 18 November.
