Bruce Willis is the most wholesome grandfather.

The 69-year-old retired actor was captured in newly-posted pics sharing the sweetest moment with his granddaughter, Louetta, the 12-month-old baby of his oldest daughter, Rumer Willis.

Rumer, 35, took to social media this week to celebrate the milestone of her baby girl’s first birthday, and her post included a precious photo of Louetta bonding with her “Papou.”

As seen in the Instagram post shared on Saturday, April 20, Bruce beamed with joy as he cuddled the infant in his arms in one of the photos. His former wife and Rumer’s mom, Demi Moore, was also featured in the post, smiling down at Louetta in another shot, which looked to be taken during the holiday season.

“Oh my tiny tender daughter, I CANT BELIEVE YOU ARE 1 ✨” Rumer wrote in her Instagram post on Saturday, calling this last year, “the best of my life.”

“You are the most delicious, most beautiful, smartest, funniest, sweetest girl I know,” continued Rumer, who shares the infant with partner Derek Richard Thomas. “Every day you grow and learn more and you are my greatest teacher and my deepest love.”

Elsewhere in the emotional post, Rumer gave a shoutout to the family members in Louetta’s life, including her mom Demi, or “Ya Ya” to Louetta. Rumer also mentioned her sisters Scout and Tallulah, plus half-sisters Mabel and Evelyn for “being the greatest aunties.”

She also gave a nod to Bruce’s wife, Emma Heming Willis, whom she called Louetta’s “bonus Gma,” while praising the Die Hard actor and close family friend Eric Buterbaugh for being “the best Papous.”
