Rachel McAdams says any man she dates must be very flexible.

The 36-year-old actress is currently single after her relationship with Canadian music manager Patrick Sambrook ended last year but she's on the lookout for a new guy and has three specific things she requires in a prospective lover.

When quizzed on what she looks for in a man, she said: ''There are three cardinal points: kindness, humour sense and flexibility. Apart from a taste for adventure. I'm content with that.''

Rachel admits she has on occasions thought about having a baby in the future and has contemplated what sort of parent she will be.

But first the 'Southpaw' star is concentrating on finding the right man and making sure she's the best partner she can be to him.

In an interview with Spanish newspaper El Mundo, she mused on motherhood: ''Well, we all think about it, sooner or later. First we imagine the type of partner we want to be ... Then, when the time is right, it will be the moment to figure out the type of mother you want to be.''

Rachel has previously been in relationships with actor Ryan Gosling, Josh Lucas and Michael Sheen, who she met on the set of Woody Allen's 'Midnight in Paris' in 2010.
