The former Playboy playmate admits she can't wait for her friend to give birth to her first son - her child with husband Hank Baskett - later this month.
She said: "I'm super-excited for her. She's less than a month away. It could happen anytime."
However, much to Holly's unhappiness, the former 'Girls Next Door' co-stars have spent little time together since Kendra found out she was expecting a baby as they no longer live close to one another.
Holly added: "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.
"Hopefully next month, I'll get to see the baby. We text all the time and she's really excited. She's happy as can be."
