The 36-year-old blonde beauty and her 42-year-old party promoter husband Pasquale Rotella tied the knot in 2013 and the former Girls Next Door star opened up about her struggles with mommy shaming and parenting in the limelight.

“I think every mom feels judged these days. Somewhere along the line, parenting got really competitive. I get a lot of it on Instagram. I can’t post any picture of my daughter without someone commenting that I’m not being a good mom,” she told Yahoo! last year.

Now, with little Aurora looking more and more grown by the minute, the proud mom is taking a stand.
