Ariana Grande has returned the huge engagement ring given to her by ex-fiance Pete Davidson, but she's keeping their pet pig. The pop star bought the tea cup pig, Piggy Smallz, as an emotional support animal. But when it came to her 3.3 carat diamond ring, a published report said "there was no struggle over" who'd keep it. Grande returned the $93,000 diamond ring to the "SNL" star. Unfortunately, the couple can't return the 15 tattoos they got to express their "forever" love.
