"I can tell you, we are working on an amazing script," Banks told ET of the follow-up to her and Lohan's 2000 TV movie. "I've been hitting up Miss Lindsay Lohan in her DMs, like, 'You in, boo?' and I think she is excited to come back."

So did Lohan officially say yes to joining the sequel?

"Did you, Lindsay?" Banks joked. "I think she did."

Life Size 2 will see Banks reprise her role as Eve, a doll who is magically awoken to help a young woman learn to live and love again, while also experiencing her own ups and downs in the real world. As of now, Banks is trying to figure out how they can best incorporate Lohan's character, Casey Stuart.

"The weird thing is, Eve's kind of stuck in time. So, she's going to be a little older, but hopefully not looking that much older!" Banks shared. "Whereas when Lindsay started, she was a little 10-year-old girl. Now, she's a woman! So, we have to evolve that and figure out who she is today."

Banks never imagined that she'd be making a Life Size 2 and originally even turned down making a sequel.

"I turned down Life Size 2," the America's Got Talent host revealed. "I don't know if I've said that, personally. 15 years ago, I turned it down!"

While she didn't go into detail, Banks did mention that fans will get to find out why in her upcoming memoir, set to be released in 2018.

Aside from her many projects, Banks is also adjusting to life as a new mom.

"I'm in heaven with my lil' pumpkin," Banks gushed. "My heart is on the outside and he walks around. I'm like, that's my heart!

Banks and her boyfriend, Erik Asla, welcomed their first child together, a son named York, in January, via surrogate. Since his birth, the America's Next Top Model host has been obsessed with her little guy and found that the most surprising aspect of motherhood is "how you can love something so much."

"You just wanna wake this being up in the middle of the night to cuddle with it, but know that you shouldn't," she gushed
