This week Poland's Prime Minister Donald Tusk demonstrated he knows how to charm and break the ice with celebrities.

When meeting the famous Hollywood actor George Clooney, a staunch critic of Donald Trump, he self-deprecatingly introduced himself by saying: "My name is Donald. It's not my fault. It wasn't my choice."

Clearly amused the movie star laughed and replied, "It's okay". In turn, his wife - human rights lawyer and activist Amal Clooney - greeted Tusk: "Good morning, Prime Minister, nice to meet you," before adding in Polish: "Good day."

Earlier, the Prime Minister published a joint photo with the couple, captioning it with the laconic comment: "Amal and George Clooney agree with me that Poland is the best place on Earth." This was a reference to his own words spoken at the conference, where he argued that Poland today is "the fastest growing country in Europe and one of the most ambitious nations on the continent" and "the best place on earth to live and fulfil your dreams."

The beef between Clooney and the US President Donald Trump has a long history. For years, the actor has been openly critical of the president - both his views and his governing style.
