Lady Gaga has come under fire for her recent 25 lbs weight gain, but it seems that she has had the last laugh.

Lady Gaga, 26, looked sensational as she displayed her curves in a red Versace dress in Milan yesterday.

The very revealing designer dress clung to Lady Gaga’s figure in the all the right places.

With her auburn hair tumbling around her shoulders and her lips and talons painted red, Lady Gaga appeared to be channeling Jessica Rabbit in her scarlet attire.

The songstress accessorized the form-fitting ensemble with some signature Versace accessories, including a large medallion belt featuring the company’s logo and a black leather bag.

Lady Gaga also wore a pair of cat-eye sunglasses and a necklace featuring a red chilli pendant.

The pop star was visiting the company’s Vice President Donatella Versace at the Versace headquarters in the fashion capital of Italy.

Donatella Versace, 57, looked thrilled to be spending time with the singer as they posed for photographs out the front of the building.

The moment was also captured by photographer-to-the-stars Terry Richardson.

The platinum blonde and perma-tanned fashionista also wore one of her own designers, slipping her tiny figure into a tight corseted leather dress.

She paired the attire with some gaudy knee-high boots featuring giant crucifixes on the front.

The designer had a heavy-handed application of make-up, including a kohl-rimmed eyes and a nude lipstick on her pout.
