"Taylor Swift is once again opening up about her love life. While making a stop at New Jersey's MetLife Stadium during her Red tour, the 23-year-old singer revealed to Rolling Stone that "the only love worth being in" is "mad love." PHOTOS: Taylor Swift's romantic history "I am getting to the point where the only love worth being in is the love worth singing about," the "I Knew You Were Trouble" singer said backstage. "And kind of mad love. I think that for me, when you experience something that's worth writing a song about, chances are it's the same kind of intense feeling that someone else has felt, and it has led them to be sitting on a bedroom floor crying, or walking through a crowded room feeling alone or feeling misunderstood by the person who's supposed to know them better than anybody else."

Taylor Swift's best surprised faces She added, "Those are things that make you feel really alone, and if someone's singing a song about that feeling, then you feel bonded to that person, and I guess that's the only way I can find an explanation why 55,000 people would want to come see me sing." Singing about her exes, of course, is nothing new to her fans. In both her 2010 Speak Now and 2012 Red albums, the songstress has admitted to leaving clues in the CD's notes on which boyfriend she's actually singing about.
