Kendra Wilkinson's second pregnancy has been ''brutal''.

The former Playboy model - who already has four-year-old son Hank Jr. with husband Hank Baskett - is due to give birth to a baby girl in the coming weeks and she admits it is becoming a struggle to move around.

She said: ''It's easier on the mind, harder on the body. It's been brutal. I think because little Hank stretched me out, I know that sounds pretty gross, but he stretched me out all the way! I think she got a chance to sit lower faster, so she's been on my pelvic bone all pregnancy.

''Like, I'm seriously done! It's over, like my life is over right now. I'm trying so hard not to be bedridden.''

The 28-year-old beauty is particularly worried about her waters breaking and going into labour when she is out at an event.

She told E! News: ''The weirdest thing is standing about to go on a red carpet and praying that this pee I'm peeing isn't my water breaking!

''I literally cross my legs hoping my water isn't breaking! It's pee, it's fine.''

Kendra and Hank are doing their best to involve their son in the pregnancy.

She said: ''Little Hank is super excited. We're trying to get him to feel like he has a role. I'm the mom, Hank's the dad and he's the protector. I want him to feel empowered through this and feel loved still.''

And the couple have a shortlist of names for the new arrival, but won't choose one until they meet her.

Kendra said: ''We have a good five [names] We have a top five. We're going to have to see her and name her.''
