Jane Krakowski: 'I could not stop crying' over '30 Rock' finale

The cast of "30 Rock" knew the end was nigh as they filmed the show's final season, but that didn't make shooting the series finale any easier.

"It was a very tearful goodbye," Jane Krakowski, who played Jenna Maroney on the long-running series, revealed during a Thursday morning visit to TODAY. "It sort of didn't set in as a reality until we got to the final episode. Then there were so many tears from the read-through on. I cried so much I became known as the John Boehner of '30 Rock.' I could not stop crying."

The tears are bound to flow again as Krakowski joins her "30 Rock" pals one more time Thursday night.

"Tonight … for the series finale, we're all going to get together and watch it together," she said.

In addition to their own farewell performances, they'll watch a guest appearance from TODAY's own Savannah Guthrie in the series sendoff. According to the always-diplomatic Krakowski, she was "wonderful" in the episode, but it's tough to pick a favorite among the many TODAY-anchor cameos over the years. "I've had a few magical moments with Matt (Lauer on the show) as well," she admitted.

The series finale of "30 Rock" airs Thursday at 8 p.m. on NBC.
