Kendra Wilkinson isn't the only one anxious for her to give birth to her first son this month.

"I'm super-excited for her!" Holly Madison told at the opening of Crystals in Las Vegas Thursday. "She's less than a month away. It could happen anytime."

The former Girls Next Door roommates, however, haven't had much quality time since Wilkinson, 24, and her husband, Indianapolis Colts receiver Hank Baskett, 27, found out she was pregnant in June.

"It just sucks that she's all the way in Indiana because I want to be there, but I’ll see the baby soon enough," Madison -- whose E! reality series Holly's World premieres Sunday -- told Us.

Their long-distance friendship isn't going to stop her from babysitting, she jokes.

"Hopefully next month, I’ll get to see the baby," she told Us. "We text all the time and she's really excited. She's happy as can be."
