Happier both personally and professionally than she's been for a while, Jessica Simpson says it is all because of her boyfriend Tony Romo, who by the way she says is her "perfect guy."
"I just told him today, 'You're the love of my life,' " she confesses to PEOPLE. "I don't really ever say that to anybody."
Jessica also co-wrote a song for the love of her life called, "You're My Sunday," which is featured on her new country album, Do You Know (out Sept. 9).
