Designer Christian Siriano and his boyfriend Brad Walsh went all out for Halloween this year. They dresed up as Ariel and Prince Eric. Christian Siriano posted the photograph on his Twitter account earlier today. You can see a larger photo of their costumes here. It sounds like they were hosting their own Halloween party this year as singer Kat DeLuna tweeted, "On my way to my boos @csiriano and @bradwalsh Halloween party!!!"
