The 28-year-old reality TV star, who already has a three-year-old son, Hank Baskett IV, with her husband Hank Baskett, finally confirmed today (31.10.13) that she is expecting her second child next year, and revealed she very excited even though she is currently vomiting every 10 minutes.

Kendra told viewers the 'TODAY' show: "'Kendra on Top,' naughty, naughty, that's what got me pregnant with baby number two. We planned this to be right after the season, so I'll have time to puke. You know, be in a cave.

"I'm really at a great stage. Not physically. I'm in the bathroom every 10 minutes."

Kendra has shared her joy with her Twitter followers and posted a picture of herself holding her positive pregnancy test with the caption: "Round two. Here we go."

The former Playboy model's second pregnancy has been fairly dramatic to date as her family recently revealed they were very upset about hearing the news via the media.

Kendra previously gushed about her desire to expand her family.

Saying back in August: "We are trying, we are going to start now. This is my first official announcement! We are very excited about making the decision to try!"
