'One Life to Live' vets to guest star on 'Castle'

LOS ANGELES, Nov. 7 (UPI) -- Former One Life to Live co-stars Kassie DePaiva, Tuc Watkins and Nathan Fillion are to reunite on Fillion's television mystery series Castle.

DePaiva and Fillion announced the news via Twitter, but they did not say when the episode is to air. Castle is now in its eighth season.

"ONE LIFE TO LIVE is back!!! Just kidding! Shooting #castle @NathanFillion @tucwatkins #oltl," DePaiva captioned a photo of herself with her fellow, ex-soap stars.

"22 years ago, I was 22 years old, and working my ass off with these two. Thanks for doing this, you guys," Fillion tweeted.

One Life to Live was canceled in 2012 after more than 40 years. It was briefly revived as a web series in 2013 before it was scrapped again.
