While most brides are decked out in white from head to toe as they walk down the aisle, few may give much thought to the most important white-colored accessory of all – their teeth. But one lady is sure to have a sparkling smile as she exchanges vows.

In a recent YouTube question and answer session, bride-to-be Katy Perry, who is engaged to funnyman Russell Brand, revealed that she’s obsessed with her pearly whites.

“I brush my teeth all the time,” the songstress said. “I wanted them to be, like, Britney Spears white. I used to grow up seeing her music videos, like, ‘What does she do? Does she get a new set of teeth all the time? They’re so white!'”

Ladies looking to brighten their smiles before their wedding can use a teeth whitening system from GoSMILE or SuperSmile. However, for a quick fix, girls can swipe on a bold lipstick – as long as it’s the right shade.

According to Allure.com, blue-based red and berry shades make teeth appear whiter, while formulas with golden or orange undertones will make teeth seem more yellow.

Youngblood offers several shades of lipstick that boast blue undertones, including Kranberry, Rosewater and Pink Quartz.ADNFCR-3538-ID-19914112-ADNFCR
