It's an announcement we hope you've been excited about, because we have been anxious to make it official!

Peter Facinelli, affectionately known as Carlisle Cullen from the Twilight Saga of movies (or maybe Mike Dexter for the Can't Hardly Wait crowd), is the celebrity guest for the 2012 edition of Women's Night out!

Facinelli will make his exclusive appearance at Harvey Convention Center on Saturday, March 31, on a night just for the ladies, who will be able to enjoy his speech, various vendors' booths, special presentations and more, all presented by Townsquare Media.

And we've got to give a lot of props to all of you who played along with us in guessing our celebrity guest last week. It didn't take long for many of you to guess who the star was who was going to headline Women's Night Out this year.

But, of course, there can only be one winner, and we're happy to congratulate Erin Taylor! Erin took a stab at Facinelli at 2:15 p.m. last Wednesday, just a little over six hours after we posted the first picture of Carlisle, ahem, Peter. Needless to say, very impressive!

Erin, who posted the guess on Mix931fm.com, won an exclusive meet-and-greet with Facinelli for the night of the event, so don't forget your Sharpie! Erin's guessing prowess was also announced on Kidd Kraddick this morning on Mix 93.1.

We'll have plenty of coverage of Women's Night Out leading up to the event, including more stuff to win that you'll want to keep up with!

In the meantime, here's Peter Facinelli (Carlisle) and Elizabeth Reaser (Esme) talking about Twilight: Breaking Dawn Part 1:

And for the Can't Hardly Wait fans, here's "Mike Dexter" opposite Jennifer Love Hewitt in the classic 1990s teen movie:
