Farrah's Ring

Did anyone watch teen mom og last night? Who the hell spends $32,000+ on an engagement ring, especially one for Farrah?! Do you think she had to buy it? Or did her fiance buy it for her? I watched that episode with my bf last night and we were just floored that anyone could be in a relationship with her! Or spend that much money on her ring. Like seriously. She was saying the $1,500 rings looked cheap...so not in touch with reality!
