The former 'Girls Next Door' star says she has no desire to comment back.
Kendra Wilkinson could have ignited a major Twitter feud with her recent NSFW tweets about Hugh Hefner's other ex-girlfriend -- but Holly Madison says she "didn't really get emotional" about her former Girls Next Door co-star's online outburst.
Last week, Madison spoke out about her time at the Playboy Mansion, saying she felt "a lot of fear" while living there. Wilkinson then blasted those claims with a vulgar rant. "She wasn't in fear with that d**k in her a** for a paycheck," the 30-year-old reality star tweeted. "That b**ch is in fear now knowing so many of us saw her doing some nasty sh*t. She's embarrassed and in shame. She was the clean-up girl."

Wilkinson later deleted the tweets and issued an apology.
On Tuesday, Madison told Jenny McCarthy on her SiriusXM radio show that she doesn't see the point of responding to the crass messages because Wilkinson is not in her life anymore. "It's gross but I feel like anybody can come out this day and age. I'm like, I'm used to it," she explains. "When it's coming from her, I have my suspicions as to where this is coming from and it's all really hypocritical."

The 36-year-old adds, "I was there before her, I saw a lot of things she never saw too."
Madison also believes that Wilkinson's rant stemmed from her connection to the Playboy Mansion. "She still works in that world and she has a different viewpoint on things," she insists. "You're still in that world and you're still dependent on that in a way."
"I just don't feel like I want to lower myself and go there and respond other than, 'I wish you the best.'"

As to whether Madison would consider contacting Hefner, "I feel like I don't really care," she admits. "Even after I left the mansion, I realized that this person I cared about was so much an invention in my head. ...I don't know this person."
Both Madison and Hefner have moved on since their breakup in 2008. The 90-year-old Playboy mogul is now married to 30-year-old model Crystal Harris, and Madison is expecting her second child with with husband Pasquale Rotella. "I've moved on and he's moved on and I can't even imagine wanting to say anything," she shares.

Following Wilkinson's Twitter rant, Madison also released a statement to ET. "I want no part of a one-sided argument or feud where one woman lives to demoralize and degrade another woman," she said. "For those with unresolved issues, therapy works. You should try it."
