"MythBusters" fan-favorites Kari Byron, Tory Belleci and Grant Imahara are leaving the series after ten years, the show's hosts Adam Savage and Jamie Hyneman announced on last night's episode.

The axed trio took to Twitter saying the Discovery Channel show had decided to take a "new direction."

"I guess you guys are finding out the news right about now. After a decade of the MythBusters, we are no longer with the show," Kari said in a series of tweets. "Thank you to all the fans who have supported us. The show is taking a new direction. It was an amazing run. I learned so much about myself and the world. I love you all @MythBusters. I am sad for an ending but there will be exciting new adventures for us."

When asked by FOX411 the reason the three would not be returning next season, a representative for the show failed to elaborate what new direction the show was planning.

"Kari, Tory and Grant have been an incredibly important part of 'MythBusters' for over a decade," a senior publicist with Discovery told FOX411 in an email. "From explosions to car crashes to even more explosions, this trio has helped shape 'MythBusters' into the Emmy-nominated series it is today. Everyone at Discovery wants to thank them for their tireless work busting almost 1000 myths, and we wish them all the best on their future endeavors."

There appears to be no hard feelings between the show and its former stars. Bellici wrote on Twitter, "It's been an amazing ride for 10 years! We couldn't have done it without you guys. You're the best fans anyone could wish for. Thank you."

"Thanks @MythBusters for allowing us to teach science in a whole new way," Grant tweeted. "Also, explosions. Now, on to the next adventure!"

Savage and Hyneman will resume as the show's only hosts for the 2015 season.
