Jessica Simpson has a lot on her plate at the moment, with raising two kids, heading a fashion empire and planning her upcoming wedding to fiancé Eric Johnson. But the blonde reveals she “couldn’t be happier.”

The former reality TV star is gearing up to add home and baby features to her fashion line, which already includes clothing, footwear, handbags and jewelry. Her billion-dollar company is a huge success — so what’s her secret?

“Well, I think that I can relate to every woman out there,” the singer told Today. “I have been every size there is, so I know how to dress every body type.”

She added, “I truly believe that it’s not just about high fashion. You know, we all need pieces in our wardrobe that are fashionable but accessible, wearable, you know, and affordable. I think that’s really what has made the brand such a success.”

It sounds like some of that cash she’s raking in is going to be put towards a big wedding to her fiancé and father of her children. “It’ll definitely be extravagant,” Jessica said of the nuptials. “I don’t do things small.”

Aside from wedding planning, her life is all about a balance of family and business, including a return to singing. The 33-year-old is building a recording studio in her house to refocus on her music. She hasn’t released a studio album since 2008’s ‘Do You Know’ (if we exclude her 2010 Christmas album), but that could change very soon!

Asked what present Jessica would say to her past self about the future, she laughed and responded with, "Hold on! This is going to be a long ride."
