Ever since Amber Rose and Wiz Khalifa announced their split, there have been numerous dating rumors surrounding them both. Despite their possible side romances, Amber has shown that her affections for Wiz are still present in her heart, and she recently showed interest in him once again.
Wiz posted a nude photo of himself in the shower while pouring a bottle (possibly alcohol) on his head. Amber took notice of the Wiz Khalifa nude and "liked" the photo. Given the fact that Instagram "likes" are simply a way for someone to show that they like the visual aspects of a photo, when you "like" a nude, the admiration may be a bit more deeply rooted.
