The first-time father is basking in all the emotions of becoming a dad.

Aunt Becky from Full House has finally weighed in on the newest member of the family.

On Wednesday, Lori Loughlin posted a sweet Instagram video for brand new dad (and still Uncle Jesse), John Stamos. Stamos and wife Caitlin McHugh welcomed a baby boy, Billy, on April 10.

"Hey, hey. Mr. Stamos," Loughlin says in the video. "We all want to come and meet Billy, but see you're home with a newborn baby and I'm hanging out with the cool crowd."

Stamos was touched.

"Can’t wait for Billy to meet his great, great, great Aunt Becky and clan," he posted on Instagram. "XOXOX @daviddobrik @oliviajade @bella and especially @trishapaytas"

Stamos, who famously played the eternal bachelor Jesse on Full House, is catching up to the character on the revival, Fuller House, in which he reprises his role as a happily married man with two kids. 

The real-life Stamos is head over heels for his son, telling ET that he's "so emotional and excited" about the little guy.

"I woke up this morning and I sang him 'House at Pooh Corner,' the Christopher Robin [song]," he recently told ET. "I started crying. It was great."

He added, "It's more beautiful than I imagined. Everything is more colorful, more exciting. Music, you know, sounds better. He's just a beautiful little boy."
