The Pretty Little Liars season 4 finale will be full of surprising developments and answered questions, according to star Ashley Benson.

Benson, who plays Hanna on the ABC Family series, told GossipCenter at a Monday event that the season finale is "insane."

"I think a lot of people are going to like it. All the questions will be answered," Benson teased. "I can't tell you much more because I don't want to ruin it, but it's really good and season five is going to be completely different. People are going to be pretty shocked."

With Pretty Little Liars wrapping production on their fourth season, Benson and her co-stars have bonded as friends as well as co-workers.

"The girls and I are so close still, which is really amazing," Benson said. "We have so much fun on the set, I'm always joking around. I'm not the serious one. I'm constantly ruining takes because I can't hold in my laughter. We just hang out every day. It's been five years so it's pretty crazy."

The actress told E!Online that she will be filming another appearance on the Pretty Little Liars spinoff show Ravenswood. She admitted that even she can't keep up with whether or not her character Hanna is together with Caleb or not on the show.

"I actually don't know what I'm doing at all when I'm over there, they won't tell me anything. I'm like, wait are we together? Are we not together? What am I doing? Am I crying? I don't even know what I'm doing," she said.

Pretty Little Liars returns for season 4B on Tuesday, Jan. 7 at 8 p.m. on ABC Family.
