Kristen Wiig surprised fans on Mother's Day by hosting the “Saturday Night Live” Season 45 finale.

Wiig joined “SNL: At Home” for its Season 45 finale over the weekend. The show featured a guest appearance from Alec Baldwin as Donald Trump, and Wiig opened the show with a home-taped monologue.

She was laying in bed sleeping and announced, “Ladies and gentlemen, Kristin Wiig!”

“What? Me? Host? Now? Okay,” she continued, then smiled and jumped out of her bed while wearing pajamas.

“Let's do this!” she added.

Wiig danced around various parts of her house and eventually got down on the floor on a fur blanket surrounded by candles because she wanted to get serious with “Mother’s Day.”

“This is the Mother's Day show, and at SNL, it's a very special time to celebrate moms,” Wiig said.

Since she couldn’t be with her mom, Wiig shared her message for her on the show.

“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,” she continued.

Wiig then went on and lifted up a plate of cooked chicken breasts. She recalled how her mom would always tell her that “babies love that chicken.”

“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,” she added.

Wiig wrapped up her stint by singing a lullaby that her mom used to sing to her during bed time. She sung “Hush Little Baby” like a Broadway performance.

Tom Hanks hosted the first episode of “SNL at Home” after being on hiatus for five weeks. The “Cast Away” actor also delivered a monologue during his stint.

Hanks’ show averaged 6.7 million total viewers and a 1.46 rating. It was the second best for the season next to Eddie Murphy’s hosting on Dec. 21, which drew almost 10 million viewers.
