ashlee simpson and pete wentz with son bronxAshlee Simpson-Wentz has said she doesn’t know how 2009 could possibly top 2008.

Last year saw the singer marry boyfriend Pete Wentz and the couple welcome their now six week old son, Bronx Mowgli Wentz.

Ashlee and Pete rang in the New Year hosting the party at Pure nightclub in Las Vegas but she told reporters: “I don’t know if I can have high expectations for 2009 because 2008 was so good. It was the greatest year of my life.”

But that’s not say she doesn’t have some plans: “[I want to] go back in the studio [to] start working. Not quite yet, but soon.

“[At the moment] all my focus is on my son. Every day, being a better mom and learning with him. It’s an incredible experience.”
