Rebel Wilson is Will Sage Astorhaving a pitch perfect time as a new mom.

The Bridesmaids actress recently detailed a new major milestone her daughter Royce, 7 months, has reached. And, through it all, she'll be right by her baby girl's side.

"Royce is so cute, she's teething right now," Rebel exclusively told E! News at the Casamigos Cristalino launch of dating app Fluid. "So I was up at like, 4:45am this morning with her. She's the most adorable gorgeous baby."

As for what motherhood has taught her so far, the Pitch Perfect star touched on her own experiences with mom Sue Bownds.

"I really appreciate my mom a lot more, I think, by going through it and being a mother myself," Rebel said, before adding of Royce, "I just want her to be awesome, and happy and healthy."

Rebel isn't going through the parenting journey alone, noting her fiancée Ramona Agruma has held her hand from the start.

"Ramona is so loving and thoughtful, and she's just such a good partner," the 43-year-old continued, "It's kind of like she came into my life at the exact right time and then the surrogate getting pregnant and Ramona was really into that. So it was kind of awesome. It just kind of came together at the right moment."

However, meeting someone like Ramona took time for Rebel, who launched dating app Fluid with BFF Carly Steel after being inspired by her own dating experiences.

"I only dated men, but I didn't think in my mind like I was 100% straight," the actress explained. "But I didn't know how to categorize that. So that kind of scared me off, I guess exploring my sexuality and stuff. We wanted to make an app [where] you don't have to label yourself—very modern. It's kind of a new complex, nuanced way to look at sexuality."

If Fluid had existed all those years, Rebel said it might've changed how she approached romance.

"I just think it would have, because there's no labels it would have been more chill way to date," she added, "I would have dated some women probably."
