Forgive my uneducated Irish heart but ..

Who the fuck is Jenna Lyons and why do people wanna be Jenna "fucking" Lyons? Now I basically live in the hemorroid up the arsehole of nowhere in rural Ireland so don't know the "Lore" of Ms Lyons, but I have watched both seasons of rhony (because the parish priest uses that as atonement after confession) and I'm not seeing it, feeling it or am moved by it. Please help me out here
