Paramore have announced that bassist Jeremy Davis will be absent from the group's short run of radio-sponsored U.S. holiday shows, which kicks off tonight in Philadelphia. Davis and wife Kathryn Camsey Davis are expecting their first child in a matter of weeks, and have opted to spend time in Kathryn's native England with family. Filling in for Jeremy will be Justin Meldal-Johnsen, whose performance credits include Nine Inch Nails, Beck, and The Mars Volta, and who most recently produced Paramore's eponymous new album.

Check out a message from the band below, which also reveals a January release date for their newly-reshot "Ain't It Fun" video:

"Hello P-more family!

Lots to talk about, so little time to talk about it all!

First of all, we can't say thank you enough to everyone who came to see us on The Self-Titled Tour. Honestly, it couldn't have gone any better. Big shows, loads of people, new fans and old school fans! To the long-time super hardcore dedicated bunch: it's a little nuts to think that we've been touring for 8 years now and you have stuck with us through thick and thin. Seeing your faces up front will never get old and your pictures from the shows were both incredibly humbling and gratifying. To those of you who've just discovered what it means to be a part of our family, it was amazing to see you all out there and hear you sing along to all the songs - even the deep cuts! Thank you to everybody who made that tour what it was and what it will forever be. We will most definitely see you again and hopefully sooner than later!

Some of you will see us this month on our little holiday run. All the Jingle Ball shows and radio shows... we've got 'em covered. One little thing though... Maybe you already know but just in case you don't: Jeremy and his wife, Kathryn, are getting ready to have their baby girl! We're weeks away now. We all thought that maaaaaybe that was a little bit important and everybody told him that if he needed to bolt, we'd completely get it and we'd cheer him on from over here and swing the holiday shows without him. So he won't be with us at these Christmas shows but now he can go ahead and be with his family in England and he and Kat can bring their little one into the world! Make sure to send Jeremy lots of love and pictures from the shows and messages for him and Kat and the 1st P-more baby. We can't wait to meet her!

Maybe you're wondering how the heck we're gonna play shows without Jeremy slapping the funky funk out of his bass? Don't worry… we took care of it. We're psyched to let you know that for all the dates in December, our producer/friend/ridiculously talented musician, Justin Meldal-Johnsen will be joining us! So Philly, you will see him with us tonight! It's gonna be a lot of fun and a really memorable bunch of shows. This is an exciting time for our band. Having our best friend become a dad, playing some shows with someone who really helped Paramore get to where we're at today, and to be able to celebrate the year that we've had and end it only to start another great year just doing what we do. Check the tour dates on our page to see if we're playing any holiday/radio shows near you and if we are, come hang and celebrate with us!

Speaking of next year… We'll be releasing a brand new single along with a new video! "Ain't It Fun" will officially be out some time in January :) Thanks for being patient with us. We just shot the video yesterday in our hometown and now we're just waiting for all the editing, revisions, and approvals to start! No official release date for the single has been set and as usual, the video release will follow suit. We'll keep you posted! This one is gonna be a good time.

Alright. See you at the show!

Hayley & Taylor (with Jeremy in spirit all the way from ol' Blighty!!)"
