The comediennes have been friends for 20 years and play siblings in the upcoming film "Sisters" and Poehler said they always lean on each other for support and advice, reported Female First.
"Neither Tina or I have sisters in real life. We are each other's chosen sister. Like most sisters, we've never dated the same guy and we're great in photo-shoots and fittings because we know what will look good on one another," the 44-year-old actress said.
"We're kind of like sisters and our parents are show business. We call each other to complain about how mom and dad have treated us at Thanksgiving."
