While Amanda opted for some kind of nod to the 80s in her all-white power suit, Alesha was bold and beautiful in a zinging orange fit-and-flare skirt with a matching tucked-in jumper.
Amanda took to Twitter to talk about her look, which cost £1,222 just for the Alexander McQueen jacket alone. Ouch. She also compared her look to a famous Sex and the City character, writing: "Homage to Samantha Jones?"

Her makeup artist Christian Vermaak also revealed how he got her bold and glamorous makeup look, tweeting: "Today @Amanda_Holden Hair and make-up by me using @DolceGabanna lip and @Guerlain skin & @MacCosmetics lashes #BeautyBackstage."
Alesha also took to Instagram to thank her makeup team for "today's look", which consisted of ultra-long fluttery lashes, bronze eyes shadow and nude lips.
