The former Girls Next Door star, who now has her own solo reality show, announced on Thursday (31 October) that she and husband Hank Baskett are preparing to welcome a second child.
During an appearance on US breakfast show Today, she laughed: "We planned this perfectly to be right after the season so we have a little time off and I have time to puke and just be in a cave!"
She added: "I'm not feeling physically good, I'm in the bathroom every ten minutes!"
Kendra, 28, told the programme that she is still in her first trimester and is looking forward to learning the sex of her child when she reaches thirteen weeks.
"My husband is so excited," she said. "He just thanks me every day for having his children. He takes such good care of me. I couldn't have found a better man."
Kendra confirmed her pregnancy via a Twitter picture of herself holding up a positive pregnancy test. She added the caption: "Round two. Here we go!! :)"
After being inundated with congratulatory messages, she wrote: "Thank you for all your love and support. Really appreciate it!!!"
The blonde model and her former NFL player husband are already parents to adorable son Hank Baskett Junior, three, who is no doubt looking forward to having a little brother or sister!
Yesterday, however, his main focus was on Halloween, with Kendra saying that now he's three the family are finally able to take him trick or treating and carve pumpkins. In fact, she revealed she'd be jumping straight on a plane from the New York TV studio to LA to spend Halloween night with her little man.
