“He’s so silly! Silly is definitely the best word for him,” Britt recently shared with ASOS mag about working with George, 54.

She added, “He’s a guy who always wants to be doing something and making people laugh. He loves goofing around. He plays music in-between takes. He knows all the words to [The Sugarhill Gang's] Rapper’s Delight. Every word, it’s really impressive.”

FYI: Britt is wearing a Fausto Puglisi dress and Sophia Webster shoes.
