Kendra Wilkinson says her unborn baby will be her last.

The reality TV star, who is almost in her second trimester and already has a three-year-old son, Hank Baskett IV, with her former NFL star husband Hank Baskett, only wants two children and is thinking about having her tubes tied after her second pregnancy.

The 28-year-old blonde beauty told ''No more. I might tie [my tubes] or take them out or whatever you do with it!''

The former Playboy model is planning to find out the sex of her baby soon but doesn't care if it is a boy or a girl.

She said: ''There's nothing on our minds that makes us say, 'I really want a girl or I really want a boy.

''I always said I will not have another baby until I'm in the happiest place I've been since the birth of Little Hank and this is it. It's the four-year age difference -- [our son] understands and he's asking for [a sibling].''

The 'Kendra On Top' star is more laid-back during this pregnancy even though she is battling severe morning sickness.

She said: ''The first time around, I was like 'How many months am I? What day am I at?' This time, I don't even know [exactly] when this baby is due! I have about two more weeks, maybe three [until I'm in my second trimester].''
