Paulina Rubio Buttons Up For The X Factor Premiere Party

Paulina Rubio joined her fellow judges in West Hollywood Thursday night for the X Factor season 3 premiere party.

The 42-year-old showed up to Cecconi’s wearing a white Twiggy-esque frock with sparkly beaded trim and silver buttons, buttons, buttons, all down her back, back back!

Paulina kept the sparkle theme going on her feet, wearing dusty rose colored pumps with rhinestone detailing while her hair was its usual personality-filled self.

Which judge do U think was best dressed last night???
