“While many have speculated about this, we wanted to wait until after the first trimester to officially confirm that we are expecting our first child. This is truly the most joyous time in our lives and we are excited to share the happy news and start our family.”

They got married in L.A. on May 17 and honeymooned in Turks and Caicos.

Many people have indeed speculated about Ashlee’s pregnancy before and the rumors got strong when the couple announced their marriage at a time when it came as a shock to everyone.

The couple began dating in fall 2006 and announced their engagement April 9.

Simpson-Wentz’s latest album, “Bittersweet World,” was released last month. It peaked at No. 4 on the Billboard 200 in its first week, and tracks have logged more than 19 million plays on Ashlee’s MySpace page.
