She was my girlfriend's girlfriend (yeah) I woke up in someone's bed I couldn't remember what happened last night I heard a voice then someone said Roll over baby don't be wasting my time La la la la la la la la I prayed for someone I'd recognize La la la la la la la la I didn't know that I was in for one great big surprise She was my girlfriend's girlfriend yeah She was my girlfriend's girl I turned around unsure She looked so good you could have picked me off the floor This is cool this is it I feel so bad I can't remember what we did La la la la la la la la She said 'boy you'd better open your eyes? La la la la la la la la In walked my girlfriend she jumped on the other side She was my girlfriend's girlfriend yeah She was my girlfriend's girl La la la la la la la la She said 'boy you'd better open your eyes La la la la la la la la In walked my girlfriend she jumped on the other side She was my girlfriend's girlfriend yeah She was my girlfriend's girl She was my girlfriend's girlfriend yeah She was my girlfriend's girl (REPEAT CHORUS)
