Jane meets Jane!

Jane Seymour is guest starring on tonight's all-new episode of Jane the Virgin and ET was on set to learn more about her romantic new role.

"In the show I'm playing Amanda and she, of course, has had a hit romance novel -- [just] one, which makes her an expert," Seymour reveals to ET's Brooke Anderson. "Now she's teaching class and she's teaching all these wannabe romance novelists how to do it because, of course, she knows everything."

So how did the iconic actress end up on the smash CW series? "Well when they first offered [the role] to me I hadn't seen, it but I heard it was a really wonderful show," Seymour explained. "And then of course Gina was just so classy at the Golden Globes and they won People's Choice and I went, 'Woohoo! I'm on a hit show!' I'm very, very, very excited and they've asked me to do more than one episode so that's cool."

Jane the Virgin's leading lady, Gina Rodriguez was beyond thrilled when she discovered that Seymour had singed on for a guest spot. "Jane Seymour is amazing," The Golden Globe winner gushed. "I have been in love with her for so long and when I got the deadline that she was going to be on the show, I started screaming. I was in a restaurant and everyone was like, 'This is inappropriate,' and I was like, 'I don’t care!'"
