Holly Madison shows off bump while posing with fellow Playboy vet Jenny McCarthy as the Girl Next Door vet promotes another Hefner tell all

The promo tour for her second memoir, The Vegas Diaries, kicked off in Brooklyn, New York, on Monday.

And Holly Madison got an early start to the day, turning up for a chat with Dirty, Sexy, Funny host Jenny McCarthy at the SiriusXM Studio in New York.

Her fellow Playboy vet pal couldn't keep her hands off the 36-year-old's burgeoning baby bump, which Holly proudly displayed in a tight blue dress that fitted her like a second skin.

The blonde's impressive decolletage was also prominently on show thanks to the frock's low cut neckline.

 

The new book gives the inside story of her life as one of Playboy boss Hugh Hefner's Girls Next Door, this time focusing on their Las Vegas escapades rather than their lives at the Playboy Mansion in Los Angeles. 

Both tell-alls dish about the things that E! couldn't show in the reality series that ran from 2005 to 2009.

But the new revelations angered Holly's former Girls Next Door co-star Kendra Wilkinson who took to Twitter last Monday to set the record straight.

'She wasn't in fear with that d*** in her a** for a paycheck,' Kendra ranted, among other less than complimentary things.

On Tuesday, an unrepentant Holly issued a statement to E! News defending her memoir and saying that she's 'letting go and moving on.'

She added: 'I want no part of a one-sided argument or feud where one woman lives to demoralize and degrade another woman. For those with unresolved issues, therapy works. You should try it.'

And Kendra laughed the feud off when she appeared at the satellite radio studio on Friday. 

Meanwhile, Holly is expecting her second child in August. 

She and her 41-year-old husband Pasquale Rotella, who founded Insomniac events, already share a three-year-old daughter, Rainbow Aurora.
