Adnan's Double Cross!

Is Adnan Ghalib becoming a Christian?

First we caught the photog - whose family is staunchly Muslim - sporting a rosary while out with the Queen B on Saturday night.

Then, a day later, Adnan looked to be doubling down - with two crucifixes!

Rumors of Britney Spears converting to Islam are on the tip of everyone's lips - but from the looks of things, Adnan might be a more likely candidate to switch teams!
