Life is imitating art for Baby Mama star Amy Poehler — she’s expecting a baby of her own, reports.

Just a day after the comedienne’s new comedy film, in which she plays a clueless surrogate mom, hit the top of the U.S. box office, the 36-year-old has announced she is pregnant with Arrested Development star (and Canadian) Will Arnett’s first child. The baby is due in the autumn, their spokesman Lewis Kay confirms.

Baby Mama rocketed to the top of the U.S. box office after debuting with $18.3 million during its opening weekend.
