Amal is reportedly due in June and a source close to the Gravity actor revealed that he is as "excited" and "nervous" about becoming a first-time father at the age of 55. A source told People, "George is excited but nervous. He is excited about the kids, but also has the normal amount of nerves that come with being parents."

The insider went on to add that Clooney "will be a great father because he's always had a very strong sense of family".

The source continued, "That comes from his father, Nick, and mother, Nina. If you look at it, he's had a kind of family around him, he's extremely loyal to friends."

Meanwhile, another source has revealed that Amal will be a "fantastic mother" and added, "[she] strikes me as someone who'll be a fantastic mother. Intelligent, loving, funny, smart, nurturing. She doesn't seem someone who will let kids get away with being Hollywood children."
