(Zayn). Girl it should be me. Driving to your house. Knocking on your door. And kissing you on the mouth. (Liam). Pulling on your hair. Dancing in the dark. Cos I was the only one. Who loved you from the start. (Harry). But now when I see you with him. It tears my world apart. Because. (Chorus). I've been waiting. All this time to finally say it. But now I see your heart's been taken. And nothing could be worst. Baby I loved you first.. Tight my chances. Couldn't be when he is standing. That's what hurts the most. Girl I came so close. But now you'll never know. Baby I loved you first. Louis:. Girl it should be me. Calling on your phone. Saying you're the one. And that I'd never let you go. Harry:. I never understood. What love is really like. Falling from the first time. Looking in your eyes. Liam:. But now when I see you with him. My whole world falls apart. Because. (Chorus). I've been waiting. All this time to finally say it. But now I see your heart's been taken. And nothing could be worst. Baby I loved you first.. Tight my chances. Couldn't be when he is standing. That's what hurts the most. Girl I came so close. But now you'll never know. Baby I loved you first. (Zayn). First touch. The first kiss. First girl who made me feel like this. Oh pray. It's killing me. I loved you first why can't you see?. (Niall). I've been waiting all this time to finally say it. But now I see your heart's been taken. And nothing could be worst. Baby I loved you first.. . Tight my chances. Couldn't be when he is standing. That's what hurts the most. Girl I came so close. But now you'll never know. Baby I loved you first. Baby I loved you first. Baby I loved you first. Baby I loved you first
