Ashley Tisdale spent her Thursday evening at the Wynn Las Vegas for the opening on Mizumi, the Strip's newest hotspot for haute cuisine.

The Hellcats star showed up to the resort's big night wearing a very familiar looking hot pink dress with a see-through cutout in front.

The same Brian Lichtenberg mini-dress was worn by none other that Britney Spears just a few weeks ago, during her first official day as a judge on The X Factor.

Ashley tweeted a picture of herself in the dress before the big even Thursday night, writing, "I ain't no princess but I do love pink."

Ashley was recently named Anna Faris' replacement in the upcoming fifth film in the Scary Movie series.

Who do you think looked better - 25-year-old Ashley or 30-year-old Britney?
