Lady GaGa's Victoria's Secret finale outfit felt like an ''affair''.

The 'Born This Way' singer donned a stunning Azzedine Alaia sheer lace crop top and trousers set at the end of the lingerie show in Paris on Wednesday (30.11.16) evening - where she was one of the musical performers alongside Bruno Mars and The Weeknd - and was honoured to wear such a spectacular outfit.

She shared a photo on Instagram and wrote: ''A dress by @azzedinealaiaofficial worn for #vsfashionshow. Exquisite this piece, an affair really. Feels amazing in the City of Love in a dress made with so much of it.(sic)''

The designer also created the gown she wore on the Pink Carpet ahead of the show, and Gaga was very grateful for his support.

Alongside another image, she wrote: ''Thank Monsieur ALAIA @azzedinealaiaofficial for my perfect Pink Carpet #vsfashionshow and Finale dress! I will always be grateful for not only your talent and generosity, but your simply stunning heart. there's only one ALAIA (sic)''

Gaga had a number of costume changes during the show, including a sequinned jumpsuit, worn with and without sleeves, as well as teamed with a white leather jacket, and a black and red long dress which was teamed with her very own angel wings.

But backstage, the 30-year-old star kept things simple in Victoria's Secret signature white bra and pants set and thanked the company and the models for letting her be a part of the event.

She wrote: ''Thank you #vsfashionshow for the beautiful lingerie. It was such a romantic and fun night and the women were so brave and fearless.''
