The gorgeous twosome were dressed to impress while posing outside the London Palladium before taking their seats to watch the show, which is based on Simon Cowell's The X Factor.
Model Vogue looked ready for summer in a strapless figure-hugging white frock covered in a cute red and purple floral pattern.
Despite the dreary skies the starlet ditched the tights, adding patent pointed heels while accessorising with a delicate gold necklace.
Vogue clashed her floral frock perfectly with her sweet dalmatian print clutch, holding her leather jacket in one hand and flaunting a glossy blow-dry.
Meanwhile, Brian - who seemed very pleased to have such a stunning lady on his arm! - looked pretty good himself in a navy velvet suit jacket.
The Westlife star wore navy trousers and a pale blue shirt, along with shiny black shoes and even a bow tie. Cute!
Vogue and Brian married in September 2012 in a romantic ceremony at a medieval castle in Florence, Italy. The Irish couple met in a Letterkenny nightclub in May 2011.
Meanwhile, other guests at last night's event included Simon himself, who came with girlfriend Lauren Silverman. X Factor favourites Sinitta and Louis Walsh were also in attendance.
