The 46-year-old actress hinted at becoming a mom on 'SNL' in May.

Surprise -- Kristen Wiig is a mom!  The Saturday Night Live alum is a mother of two after welcoming twins with fiancé Avi Rothman earlier this year via surrogate, ET has learned.

ET has reached out to Wiig's rep for comment. Us Weekly was first to report the news. 

Speculation that Wiig might be expecting first started in May, as she shared a Mother's Day message to her mom on Saturday Night Live: At Home. 

"I don't know if I truly appreciated my mom the first 45 years of my life. But this year I'm feeling especially grateful for her advice, her love. I'm so thankful for all the things she's taught me, like preparing me to be a mom myself. Things like breast-feeding," Wiig said, before lifting up a plate of chicken breasts. "Babies love that chicken, she would always say that."

Wiig continued, "I do want to thank my mom, and all the moms out there, who have been helping us get through this and who have been there, and who are watching over us. We thank you so much. Happy Mother's Day. Thank you, moms."

Wiig and Rothman got engaged last year, after three years of dating. See more on the star in the video below.
