Bradley Cooper and Suki Waterhouse are planning on having a baby together.

The 38-year-old actor, who is 17 years older than his stunning 21-year-old model girlfriend, is ready to start a family with the star who he began dating in February.

A source told The Sun newspaper: ''Bradley and Suki have been talking about having kids next year. They've been inseparable and Suki told friends having kids is something she's thinking about.

''And Bradley has made no secret of wanting to be a dad.''

The hunk has previously confessed his desire to one day be a father and is looking forward to having the same kind of relationship he had with his father, the late Charles J. Cooper, with his own children.

He previously said: ''Of course I have [thought about being a dad].

''I really hope I have that experience in my life. I saw how much joy fatherhood gave my own dad. So I hope it's part of my journey. You go through stages in your life, and fatherhood seems like a natural stage.''

Bradley and Suki met at the Elle Style Awards in February and have since been seen together on numerous occasions affectionately kissing and enjoying each others company.

Most recently they were seen splashing around the surf in Hawaii where they playfully messed around the in the water together, laughing in the sunshine.
