Jessica Simpson had remained mum on the pregnancy rumors for as long as possible, but on Halloween, decked out in a mummy costume, the singer confirmed the news.

"It's true — I'm going to be a mummy!" the pun-loving singer posted on her website, displaying for the world her baby bump while all wrapped up in mummy bandages. The link was posted in a tweet that read in all-caps: "!!!ANNOUNCEMENT!!!"

The confirmation comes after weeks of speculation about the singer, who had been seen in several paparazzi shots with what appeared to be an ever-expanding baby bump. Simpson's body has always been a matter of media speculation, but this time it seems she's ending all the rumors by confirming the news and getting in the Halloween spirit.

This is the first child for Simpson and fiancé Eric Johnson. The two got engaged last November and have yet to tie the knot, and it seems that their soon-to-be-expanding family could delay wedding plans a bit longer.

"I definitely see myself having a family with him, so that's exciting to think about," she told People.com about having kids with her beau, a former NFL player.

Simpson — who has dated Tony Romo (also expecting his first child with wife Candice) and John Mayer — was previously married to Nick Lachey. The two famously shared their life as a married couple on the MTV show "Newlyweds" before divorcing in 2005. Lachey recently became a newlywed himself earlier this year when he married longtime love Vanessa Minnillo. When news broke last year of Simpson's engagement, Lachey had only the nicest words for his ex-wife: "I will say the same thing I always say: I wish her the very best."

Simpson and Johnson's baby will be the second grandchild in the Simpson family: Bronx, sister Ashlee and Pete Wentz's baby boy, will have a cousin in the very-near future.
