Just days after confirming her pregnancy
, Ashlee Simpson
has postponed her summer tour.
"After careful consideration, Ashlee Simpson has decided to postpone her summer tour," the singer's publicist said in a statement Saturday. "She is committed to giving her fans the best show possible, and will be back better than ever and ready to rock in the future."
Meanwhile, the new Mrs. Wentz was in Vegas with her parents and husband for the Palms Place grand opening party where Wentz was spinning.
Playing "Power of Love," Wentz said into the microphone, "This is dedicated to my father in law Joe Simpson. I definitely have the power of love for you."
He later dedicated a song to his "baby momma," who was sitting in VIP with her mom drinking water.
