Frances Fallon has arrived — on Instagram! Jimmy Fallon's little girl made her debut on the social site on Tuesday, Feb. 17.

"Franny Fallon wishes you a happy Tuesday!" the Tonight Show host, 40, captioned a pic of the 2-month-old.

His baby girl, sweetly nicknamed "Franny," bundled up for NYC's chilly weather while sitting on her famous daddy's couch at home. The brown-haired tyke wore a hand-stitched purple cardigan, polka-dot shirt, and dark green pants, which matched her adorable eyes.

Fallon and his wife Nancy surprised the world back in December when they announced they had welcomed their second child. As they had with the birth of their daughter Winnie, they kept the baby news a secret.

"Frances Cole Fallon officially entered the world at 8:45 am on December 3rd weighing 5 lbs. 11 ounces and is 18.5 inches long. Their new addition joins big sister, Winnie Rose, 1," the couple told Us Weekly in a statement at the time. "The couple opted to keep their baby joy to themselves until their new daughter, Frances Cole, made her official debut. Both Fallon babies were born via surrogate."

After her arrival, Fallon gushed about Franny on The Tonight Show — but admitted he was "totally exhausted" because of the new addition.

"The show will now be called Early Evenings Starring Jimmy Fallon," he joked, while sharing photos of Franny from his phone. "[It will begin] around 8:30, until I pass out around 8:45!"
