Jessica Simpson has fallen in love with her American football player boyfriend Tony Romo. The singer-turned-actress admits she can’t live without the “irreplaceable” Dallas Cowboys player. She gushed, “I’m in love, yeah. Big time. It’s only been four months. I can’t believe it. It feels like forever. I love this guy.” The 27-year-old beauty also revealed that she has written a song for Tony, entitled Back In My Old Boots, as a thank you for building her confidence back up. She told America’s Glamour magazine, “Tony reintroduced me to myself. I thought that I had to be deeper, more profound and more artsy. You change with the guys you date. Come on, just be yourself. Tony taught me that because he loves me as I am. He made me feel comfortable again.”
