Yeah I think it was clear that the end of the video was supposed to show her true self (Stefani) as opposed to her fake persona (Lady Gaga).Finally watched the music video! How come no one mentioned that the paramedic calls her STEFANI?! That's Lady Gaga's real name! This means that at then end you're looking at the original person, not a made up alter persona at all!
Sorry, Pomegranates have nothing what so ever to do with Islam.
I'm pretty sure they have nothing "symbolically" to do with Christianity or Judaism either.
Islam- "Why A Pomegranate?", Patricia Langley
The heavenly paradise of the Koran describes four gardens with shade, springs, and fruits—including the pomegranate. Legend holds that each pomegranate contains one seed that has come down from paradise. Pomegranates have had a special role as a fertility symbol in weddings among the Bedouins of the Middle East. A fine specimen is secured and split open by the groom as he and his bride open the flap of their tent or enter the door of their house. Abundant seeds ensure that the couple who eat it will have many children.
Islam- "A Pomegranate For All Religions", Nancy Haught
It is important, tradition says, to eat every seed of a pomegranate because one can't be sure which aril came from paradise. The prophet Mohammed is said to have encouraged his followers to eat pomegranates to ward off envy and hatred.
