The couple, who tied the knot in a secret ceremony in New York City in front of just four guests, including the 'Skyfall' star's daughter Ella, 22, and the actress' son Henry, seven, in June 2011, are reportedly ready to expand their family as they are more in love than ever.
A source told Us Weekly magazine: "They talk about having kids together. It's about timing at this point."
The insider added: "They're so happy."
The 44-year-old brunette beauty looked besotted with her husband, 46, as they made a rare red carpet appearance at the Opportunity Network gala in Manhattan, New York on April 7, where they accepted an award for their charity work.
An eyewitness said: "When they came on stage, she never too her eyes off Daniel as he spoke."
Rachel previously admitted she hadn't ruled out having more children.
She said: "Oh, I wouldn't make one just for the sake of giving my son a sibling. But ...you never know."
The 'Lovely Bones' star also said becoming a mother to Henry, whose father is 'Black Swan' director Darren Aronofsky, had made her "much happier."
In an interview in 2009, she said: "I think being a mum and having a child has completely grounded me. It's amazing, and I've never been happier in my life. Being a mum is just delicious, and Henry is so scrumptious I could just eat him up."
She added: "And I'm a much happier person since I've had Henry, and much more balanced. I feel I have an ultimate purpose beyond anything else in my life."
