Rod Stewart is spending quality time with his baby grandsons.

The 78-year-old singer shared a photo of himself sitting with his two youngest grandchildren, Louie and Otis, during a sweet bonding session on his Instagram Story Sunday.

In the photo, Stewart held his grandsons in each arm as they sat perched on his legs.

“Louie on the right wing — Otis on the left wing — Grandad down the middle,” the doting grandfather captioned the post, tagging his daughter Ruby, who is mom to Otis, and son Liam, who is dad to Louie.

Ruby, 35, and her fiancé, Jake Kalic, welcomed their son Otis on May 9. Liam, 28, and fiancée Nicole Artukovich ’s son Louie arrived three days later on May 12. The boys are each couple's first child together.
