Ashlee Simpson says that she will not turn out like troubled pop stars Britney Spears and Lindsay Lohan. The singer has credited her fiancé Pete Wentz with keeping her “grounded.”

“I don’t see myself following the path those girls take. I’m almost 24. I’m pretty together and I’m getting married,” Simpson says. “I would never let myself get that way and I don’t surround myself with ‘yes’ people. I think that’s the most important thing.”

Meanwhile, Simpson is rumored to be pregnant with her and her Wentz’s first child.
