Holly Madison wore a $500,000 diamond tiara on her wedding day.

The 33-year-old star sparkled like a princess when she wed Pasquale Rotella in an elegant white Gregg Barnes gown teamed with the expensive jewellery at a lavish ceremony which took place at Disneyland, California, on September 11.

The pair tied the knot at popular Blue Bayou restaurant - which she booked out after-hours - that has parts of the 'Pirates of the Caribbean' ride housed in the building as they both ''love Disney''.

She explained: ''People think getting married at Disneyland has to be corny! [But] Pasquale and I both love Disney.''

Holly and Pasquale, who began dating in 2011, have a six-month-old daughter Rainbow Aurora who was a ''mini-bridesmaid'' and was carried down the aisle by a groomsman.

The former Playboy model had an outfit change for her reception party where she flaunted her figure in a figure-hugging white Roberto Cavalli gown which revealed her cleavage.

Her bridesmaids - who included her 'The Girls Next Door' co-star Bridget Marquardt and her friend and one-time Playboy Playmate Laura Croft, who stars with Holly in her reality series 'Holly's World' - wore well fitted blue Chagoury Couture gowns, with their hair hanging down.

Since getting wed, Holly has been enjoying every minute of married life.

She told UsMagazine.com: ''Married life is amazing. I'm having a good time with my family and just spending some time at home.''
