Cate Blanchett may be joining the cast of Thor: Ragnarok after all.

ET caught up with Mark Ruffalo at the BAFTA Awards Season Tea Party on Saturday, where he may have just confirmed that the Australian actress will be making an appearance as a villain in the third installment of the fantasy film.

Following the news that she was in final negotiations to join Thor, ET asked Ruffalo about his co-star.

"Your Thor 3 co-star, Cate Blanchett, is here tonight, are you happy about that?" ET asked the 48-year-old actor.

"I'm so thrilled. I saw her at the Governors' banquet here and heard that maybe she was circling, they were talking to her about the part, so I ran up to her and I was like, 'Please, please, please make this work!'" he revealed.

"She's just one of the best, and to have her play a baddie is going to be really exciting," Ruffalo added.

Last month, Blanchett, 46, was reportedly signing on for an unidentified "bad-ass female" role in her first superhero film. Yet, no official announcement has been made.

Chris Hemsworth will, of course, be back, reprising his role as the Norse god of thunder. And when Blanchett appeared on Jimmy Kimmel Live! earlier this month, she joked she was going to take over his iconic role.

"I heard you were going to be in the new Thor movie," Kimmel said. "Is that true?"

"Yes, Chris Hemsworth is busy, so I've been working out," she joked.

"Is that confirmation, or are you dodging the question?" Kimmel continued.

"No, I'm not dodging the question!" she claimed. "They're just substituting one Australian for another. Gender equality! Why can't you have a female Thor?"

"You have to understand how important these comic books are to be people," Kimmel added. "Well, listen. If you're going to be in Thor you have to be ready to fight."

Indeed!
