The blonde model and reality star walked the red carpet at the premiere of Runner Runner at the Planet Hollywood Hotel and Casino in Las Vegas on Wednesday night (18 September).
Holly wore a flirty blue dress with white trim, paired with gold strappy sandals. She kept her accessories to a minimum, letting that gorgeous wedding ring take centre stage!
The 33-year-old tied the knot with businessman Pasquale – the father of her daughter Rainbow Aurora – at Disneyland in California on 10 September.
Holly and Pasquale exchanged vows late in the evening after the park was closed for the day, with six-month-old Rainbow serving as guest of honour.
The couple became engaged in June when Pasquale proposed to Holly while they enjoyed a day out at a funfair in their hometown of Vegas.
Pasquale wasn't present at yesterday's red carpet event, but Holly found some company in the form of comedian Carrot Top!
Meanwhile, it seems Holly's just as excited as us about the news that Britney Spears is launching a two-year residency in Las Vegas from December 2013.
She tweeted yesterday: "I'm such a Britney Spears nerd. I seriously got really excited seeing her new billboards. Lol."
Lucky for Holly she actually lives in Sin City so we're sure she'll have no problem bagging tickets to see Brit on stage. The rest of us will have to start saving for a plane ticket!
