Katy Perry stole the show at the MTV EMA's over the weekend winning the Best Female award, but it was her red carpet appearance that had everyone buzzing. Katy looked beautiful as always wearing a satin dress and bejeweled headband, but it was her left hand that caught everyone's attention. The singer rocked a diamond ring on her ring finger adding more fuel to the engagement rumor fire. It hasn't been confirmed that two are indeed engaged, but after a year of dating we don't think a future wedding is too far-fetched! Check out the pics of Katy's sparkler here!
