Notaro announced the news on Facebook on Tuesday with a super cute photo of her pet cat, Fluff, keeping a watchful eye over her newborn boys, Max and Finn.
"Max and Finn Notaro arrived happy, healthy and really, really cute on June 26," the 45-year-old comic captioned the pic. "Fluff has a ton of questions about how long they plan on staying. Thank you everybody for your endless love and support."
"I am beyond excited to announce that Mrs. Notaro and I are expecting TWINS in the coming months!!!!! Weeeeeeeee!!!!!," the comedian wrote. "When people ask what exciting new project I have on the horizon, my response has been and will continue to be to just maintain all the good that I have, because I truly have it all (+ 2)."
Notaro's friend and fellow comic, Ellen DeGeneres, shared her love and support for the couple and the new additions to their family, whom they welcomed via surrogate.
"Congrats to my friend @TigNotaro and her wife @StephAllynne who are the parents of twins!" the 58-year-old talk show host wrote on Twitter. "Hello twins. Goodbye sleeping thru the night."
Congrats to the happy couple!
