Here’s what actually happened according to US Weekly:In photos of Aguilera’s incredible tribute to James — who passed away Jan. 20 — fans noticed odd streaks running down her legs.“She sang her heart out. It was a memorial service for her idol and she was nervous,” an insider explains to Us of the performance. (Aguilera, 31, has been covering “At Last” for years and called James “a true gift to music and a woman of great spirit and courage” on her website after James’ death.”“It was her proudest moment,” the source explains. “The sweat caused her spray tan to streak.”Good answer. But she doesn’t appear to be “sweating” anywhere on her body — except in the vicinity of her vagina. Do women spray tan their vaginas?
