And, with Nicole's general gorgeousness, Tulisa often comes off second best. But it was Victoria Beckham to the rescue last night as the singer stepped out in a sleek black midi dress with a leather-trim neckline from the former Spice Girl's collection.
We adored the sophisticated look but, not one to be beaten, Nicole also stepped it up in a stunning sexy fishtail gown with capped sleeves and a cutout back - from Topshop, no less.
She finished with Charlotte Olympia heels, shining waves and red lips for a look that screamed showstopping Hollywood glamour.
One thing was clear: both looks were better than Saturday night's sartorial disasters.
