But last night, both stars opted for a rather different look; Tulisa showed off what looked like a new bobbed hairstyle. Luckily (it's not her best look, right?), it was just her long hair tucked up in the old-school style. Her 20s-vibe Temperley London dress was, however, very pretty.
Nicole, meanwhile, went down the androgynous route in a loose white suit by Jean-Pierre Braganza.
She looks good in pretty much anything, but we think we prefer the show-stopping dresses.
