Romance is always in fashion for Chanel Iman and beau A$AP Rocky.

The model and the rapper headed to Beauty & Essex on Tuesday night to celebrate a pal's birthday, with Iman "looking beautiful" in a black bustier and leggings, and Rocky wearing a leather jacket, colorful hoodie and black pants, a spy dished.

Iman, 22, and Rocky, 25, "were very affectionate with each other, kissing often," the witness said. They shared a kale-and-apple salad.
