Ohhh snap! If Facebook is any indication (and it is, always) former rentboy Jason Preston is engaged. We'll make the grand assumption that it's to constantly on-again-off-again boyfriend Marc Jacobs, the fashion designer and dirty, dirty threesome-haver. Now that they're making honest men out of each other, will they still participate in those decadent ménage à trois? Probably. Will they actually see this thing through to a wedding? Probably not. Does this probably mean nothing and we should take what Facebook says with a grain of salt? Um, NO! A scintillating Facebook screenshot after the jump.
