"American Horror Story: Freak Show" star Jessica Lange has spoken about her fondness for the character she's portraying in the latest installment of the Ryan Murphy-Brad Falchuk anthology series in an interview with E! News.

Lange explains why she adores playing "Elsa Mars," saying: "I think she's the most complete. I think she's the most dimensional, the most complex...It's not straightforward ever [with her]."

She adds, "As an actor it's so much more intersting to play that than something of singular movement...It's just been great. It's been a huge character and I love playing her."

The veteran actress, who has won a Golden Globe award for her performance in the series in 2011, also mentioned how "fun" it has been for her to do a couple of musical scenes on the show's latest season. She also shared how surprised she was upon learning that people buy her songs on iTunes.

Speaking to Yahoo, Lange admitted that she never had vocal training and she never considered herself as someone who can sing.

"[But] It's also great that Ryan says, 'Here, you're going to do a David Bowie number,'" she told the publication. "So it's kind of like, 'Wow, OK, what have I got to lose at this point in my career? Absolutely nothing.' So I'll do anything, if it makes sense to the character."

Lange had said in statements earlier this year that "Freak Show" will be her last season in the anthology series, according to TV Line, but the actress said she is now open to discussions about extending her stay. 

"I think what has to happen is, Ryan and I have to have time to sit down and really talk," she said. "Because I love him dearly, and I know he wants me to continue. I don't want to, but...I don't want to say anything definitive."
