Happy birthday, Jessica Simpson! The singer, former reality TV star, and new mom to daughter Maxwell with fiancé Eric Johnson is 32 today. We've followed — and sang along with in the car and shower — the blond vocal wonder from her days as a pop princess of the late '90s and early '00s alongside Britney Spears and Christina Aguilera. Jessica had a very public relationship and split from 98 Degrees member Nick Lachey, and she's never shied away from opening up about the ups and downs of love in her songs over the years. So in honor of the birthday girl, we've got her love advice via lyrics from such hits as "I Wanna Love You Forever" and "Sweetest Sin" (the latter of which was about losing her virginity to husband-at-the-time Nick). Take a walk back down memory lane with Jess now!
