The 53-year-old 'Nigella Bites' star was spotted chatting happily with Brosnan at an Italian restaurant Bocca di Lupo, reported Daily Mirror.
"Nigella and Pierce seemed very happy to see one another and were engrossed in conversation after sitting down together for a chat. It was clear they both enjoyed the opportunity to share some time together," a source said.
Both the stars are going through a tough phase as Brosnan, 60, is coping up from the demise of his 41-year old daughter, that happened earlier in June.
