England international Bellingham netted a superb goal before then providing an assist for the Norwegian forward in their 2-1 Champions League win over Besiktas.
The 18-year-old continues to impress on the big stage and is stock continues to rise.
Haaland was giving an interview following the match when his teammate gate crashed and planted a cheeky kiss on his cheek.
Inevitably he was then asked about the former Birmingham city player.
Haaland said: "He's amazing, he's 18, he's three years younger than me, it's crazy, what can I say, he's amazing."
Despite missing a sitter earlier on in the match, the Norwegian forward netted a tap in from Bellingham's cross in what was his 66th goal in as many games.
It was a thorougly deserved goal for Dortmund who saw the match out as 2-1 winners against Besiktas in Turkey.
It could be a testing summer for the German side in next summer's transfer window who are set to lose Haaland when his £68 million release clause comes into effect.
Bellingham meanwhile is the subject of a reported £85m fee that his club have set in a bid to put off prospective buyers Manchester City, Chelsea and Liverpool.
One way or another though it is just a matter of time before these two incredible youngsters are playing for another club in Europe.
