Jessica Simpson finally has her giant baby

The longest pregnancy in history has finally ended. After a 17-month gestation period -- that's what it felt like, anyway -- Jessica Simpson has finally given birth to her baby girl!

Simpson herself confirmed the news on her website Tuesday.

"Eric and I are elated to announce the birth of our baby girl, Maxwell Drew Johnson," she wrote. "We are so grateful for all the love, support and prayers we have received. This has been the greatest experience of our lives!"

Little Maxwell weighed in at a whopping nine pounds, 13 ounces and was 21-3/4 inches long. Simpson reached epic girth during the pregnancy, admitting she put on 70 pounds -- a full month before the birth.

The name is derived from the grandmother of Eric Johnson and the maiden name of Jessica's mom.

So when exactly did this miracle occur? Sources say Maxwell made her premiere appearance at a Los Angeles hospital on Tuesday morning. "Mother and baby are doing just fine," a source told Us Weekly.

Jessica Simpson's special message from her daughter >>

The Fashion Star mentor announced her pregnancy on Halloween with a Twitter message after months of speculation and allegedly failed negotiations with tabloids to pay her for the news. She and fiancé Eric Johnson have yet to set a wedding date, but the singer/business mogul said she wanted to wait until after the baby was born so she didn't have to waddle down the aisle.

What's Simpson's next project? Dropping those pounds. She reportedly landed a $3 million deal with Weight Watchers. If true, the program could help her finally stabilize her weight, which has fluctuated wildly over the years.

Fun fact: Two of Simpson's exes are playing the parenthood game, too -- Nick and Vanessa Lachey are expecting their first baby together, and Tony Romo and his wife just welcomed their first child.
