Ashlee Simpson has cancelled her summer tour.
The 'Outta My Head (Ay Ya Ya)' singer decided to call off the shows just days after announcing she is expecting her first child with new husband Pete Wentz.
Her publicist said: "After careful consideration, Ashlee Simpson has decided to postpone her summer tour. 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 singer was in Las Vegas with her parents and husband this weekend (31.05.08) for the opening of Palms Place Hotel and Spa.
Fall Out Boy rocker Pete was a DJ at the hotel's opening party, and
dedicated a number of songs to his new family.
When playing 'Power of Love', Pete told the crowd: "This is dedicated to my father-in-law Joe Simpson. I definitely have the power of love for you."
He later dedicated a track to his "baby momma" Ashlee, who was watching his performance with her mother Tina.
