Ariana Grande and Big Sean could not keep their hands off each other on the packed red carpet at the Grammy Awards in LA on Sunday. The singer got a romantic warmup for her emotional performance of "Just a Little Bit of Your Heart," showering Big Sean with kisses as he held on to her waist and butt. At this point in their relationship, PDA is pretty much expected from the pair. Most recently, the duo shared sweet snaps of their festive vacation on Instagram in January, and they got very handsy while performing at KIIS FM's Jingle Ball concert in December. Read on to see their hot moments on the red carpet.
