Kristin Cavallari's husband "probably won't be there" for their daughter's birth.
The 28-year-old fashion designer, who already has two sons, Camden, three, and Jaxon, 16 months, with Jay Cutler, 32, admits the Chicago Bears quarterback is likely to be travelling somewhere else in the US for a game when she goes into labour.
The former 'The Hills' star said: "I'm pretty sure I'm going to be having this baby by myself. I've already come to terms with that. Well my mom will be there, but Jay probably won't be there."
But Kristin isn't nervous about being in the delivery room without him.
She explained: "Luckily it's the third one. If it were the first one, I'd be a little more nervous, but it's the third one. My mom will be there. Hopefully it will be easy [and] I'll be in and out.
"If he's not there it will be unfortunate, but I don't think I can say, 'Babe, you can't go to Green Bay or wherever you're going to be, I need you home with me.' But it's fine, it is what it is."
The blonde beauty, who just launched her new collection in collaboration with Chinese Laundry at New York Fashion Week, has had a very easy pregnancy to date.
She told E! News: "I feel great. For the most part I have my energy. I didn't throw up once and I'm very thankful for that. I think the only slight difference is I'm carrying a little higher. I'm lucky."
