(showbizspy.com) - Ashlee Simpson is pregnant, it has been claimed.
The 23-year-old singer - who recently announced her engagement to rocker Pete Wentz - is expecting her first child with the Fall Out Boy star, according to Us Weekly magazine.
"We are thrilled to confirm their engagement and congratulate this happy couple," a spokesperson for the couple said. "Beyond that there is nothing to say."
Simpson and Wentz, 28, started dating in late 2006.
"They are ecstatic and can't wait to be man and wife," a source said. "They will be getting married before the end of the year."
Wentz said earlier this month that he was open to marriage.
"When you find someone you think is your soulmate, it's inevitable," he said.
Simpson's rep had no comment on the reported pregnancy.
