Spotted outside the ITV studios in London earlier today, the blonde beauty swapped her glamorous gowns of late for a casual jeans and blazer combo.
And after having her style scrutinised in the style stakes against fellow judge Alesha Dixon throughout BGT, Amanda didn't disappoint now that the competition has come to a close.
Looking effortlessly cool, Amanda teamed her light wash jeans with an Ace of Spades logo tee and a black tailored blazer.
On Saturday night, Amanda looked incredible in a beautiful, low-cut Samuel Dougal gown as five-piece band Collabro took the coveted Britain's Got Talent title in the show's final.
With a spectacular performance of 'Stars' from Les Miserables, Collabro beat off their fellow finalists to the Royal Variety stage, including a spell-binding vocal from opera singer, Lucy Kay and a nail-biting performance from illusionist Darcy Oake - who attempted to escape from a burning, human bear trap whilst wearing a strait jacket.
If that wasn't enough, viewers were treated to an exclusive performance of Cherly Cole's new single 'Crazy Stupid Love' featuring Tinie Tempah. The Geordie beauty strutted her stuff to her new track on stage, showing off those incredible abs of hers!
As well as Cheryl, Little Mix teamed up with dance troop Diversity to take to the BGT stage and gave an energetic performance of their brand new single, 'Salute'.
