Ashley Greene wants ''no more than three kids''.

The 28-year-old actress has started thinking about starting a family with her long-term boyfriend Paul Khoury and she would like to have at least two kids and has also set a limit in her head on her maximum number of offspring.

However, Ashley wants to tie the knot with Paul first and enjoy being a married couple before she gets pregnant.

She said: ''No more than three (kids). Probably two. I'm the opposite of my mom - she had us really young, and now she and my dad are able to have fun. I want to get married, enjoy that, and then when I'm ready to completely give myself to my kids, I will. But I'm a little too selfish still.''

As well as finding happiness in her personal life, Ashley's career is also going from strength-to-strength following the conclusion of 'The Twilight Saga' franchise.

Although she is used to the Hollywood machine, the brunette beauty's family and close friends don't let her get too big an ego at home.

Speaking in the July/August issue in Health magazine, she said: ''I feel lucky to have my family, and friends who will call me on my s**t. To hear yes all the time is just not healthy ... Every single day, no matter how successful you are, there's always gonna be failure.''
