While Blake Lively's new film It Ends With Us is a tale of love, loss, pain and hope -- there was nothing but true love and joy in her real-life friendship with co-star Jenny Slate . Lively and Slate sat down with ET's Rachel Smith in New York City on Sunday, while promoting their new romantic drama , and the pair had nothing but words of kindness and support for the bond they formed during filming. "I love Jenny so much, and she was such an anchor for me in so many ways," Lively, 36, marveled.
"She's just full of love and light, but she's also deeply grounded." For Lively, her connection with Slate was fostered by how much they both "really love our personal lives a lot, and love our jobs." Video "We love our work and we take it very very seriously, and we work very, very, very hard, and we completely immerse ourselves in our work -- but who we are is defined by our personal life so much more than our work," Lively explained, "and we can be both of those things at once.
" "When you're working, sometimes you feel guilty for, you know, not being in your personal life in those hours you’re at work," said Lively, who shares four children with husband Ryan Reynolds -- daughters James, 9, Inez, 7 and Betty, 4, as well as son Olin, 1. "Just knowing that someone was having that same experience was very grounding." Slate, meanwhile, shares a 3-year-old daughter , Ida, with her husband, author Ben Shattuck .
"I deeply fell in love with her," Slate said of Lively and their time on set.
