Jenna Bush Hager seemed delighted to co-host “Jenna & Friends” with her “Sissy,” Barbara Pierce Bush — and they welcomed a very special guest.

Because the fraternal twins wrote a new children’s book together called “I Loved You First,” they decided to chat with the woman who loved them first, former first lady Laura Bush. After raising her twin daughters, Laura and her husband George W. Bush now have a whole new generation of grandkids to love.

One of them, Barbara’s oldest child Cora, told her mom that her dream was to “move next door to Grammy and Jefe.”

(Jefe, or “chief” in Spanish, is their name for grandpa George W. Bush, the 43rd president of the United States.)

“I’m thrilled to have grandchildren,” Laura said with a laugh. “For one thing, we can be with them, we can play with them, and then we can send them all back to y’all.”

“One of the things that’s been so fun is to watch you become a grandma,” Jenna said.

Laura and her husband, former president George W. Bush, now have five grandchildren: Jenna’s three children with Henry Hager (Mila, Poppy and Hal) and Barbara’s two children with Craig Louis Coyne (Cora and Edward).

The sisters say that their new book is an ode to nature … and their mother.

“Y’all remember Daddy reading to you?” Laura asked her daughters. “I loved books and I loved reading, which is why it’s so important to read to your children. I made my whole career out of it.”

Jenna said that librarians, authors and readers often tell her, “‘Your mom has been the most influential first lady. She’s inspired me.'” She added, “It matters because sometimes librarians aren’t taken seriously.”

“Librarians just say, ‘Shhh!'” Laura said with a laugh.

“You gave your love of reading to so many other people,” said Barbara.

Talking with TODAY’s Savannah Guthrie and Craig Melvin on March 25, Barbara said, “Our parents are such present grandparents. My daughter has a hilarious relationship with our dad, her Jefe. She is his number one fan, so if he’s ever having a bad day, he should just call her because she’ll laugh at anything he says.” She added that her parents are “super goofy and sweet” with her kids.

“Mila said yesterday, ‘Jefe does everything I ask.’ Nobody has ever said that before,” Jenna joked. To prove her point, Mila told her mom that she asked Jefe to paint a picture of her cat and her grandfather agreed immediately.

Jenna and Barbara sweetly paid tribute to their parents in the dedication of their book: “For our parents who taught us how to love, and for our children who showed us how much we could.”
