NEW YORK (AP) _ Jessica Simpson says the relentless gossip about her marriage to Nick Lachey drove her to visit a therapist.

``Yes I have,'' the singer-actress tells Teen People in its December-January issue, on newsstands Friday. ``I respect knowledge of the psyche. I would be a therapist if I weren't an entertainer.''

Jessica, 25, posed for the cover of the magazine with her sister, Ashlee. Both talk about the difficult challenges of the past year.

Jessica, who had a starring role in ``The Dukes of Hazzard'' movie this summer, has been the queen of the tabloids this year _ much of the coverage dissecting the marriage of the ``Newlyweds'' couple. The pair have denied persistent rumors of a split.

``Hopefully mine and Nick's story will continue for the rest of our lives, like what we vowed, through sickness and in health.''

Ashlee, 21, recently released her second album, ``I Am Me,'' and it debuted at the top of the charts. But she has still had to live down her embarrassing lip-synch disaster on ``Saturday Night Live'' last year.

``Yeah I messed up in front of everybody,'' she says. (Last month, Ashlee revisited the scene of her musical flub, performing on ``SNL'' _ really live, this time.)

However, she adds: ``I love to sing. It's a joy to me. I don't do it for anyone else _ I do it for me.

``I've had to learn that my voice is the most important one. Otherwise, I'll drown in what everyone wants me to be.''
