"How I Met Your Mother" alum Cobie Smulders has given birth to her second child with hubby Taran Killam of "Saturday Night Live."

Smulders and Killam, who announced in October through E! that they were expecting their second child, have actually had all people assuming that the due date is still a few months ahead.

On Sunday, Smulders, who is always "under the radar", subtly mentioned their little angel's arrival, while promoting her "Unexpected" film during the Sundance Festival.

"I am in Sundance and I've got a three-week-old angel. I can, certainly, relate to the movie's theme," the "HIMYM" star told Bustle. "At the moment, it is my world and it is just so rampant in the globe today. I am lucky because I have a huge support system and a blossoming career. Not every woman is given these," she added.

No further details were provided regarding their new baby; neither name or gender.

The couple, who were engaged for three years, but dated five years, tied the knot in California in 2012. Killam and Smulders are parents to Shaelyn Cado, a 5-year-old girl.

Shortly after welcoming the first baby, the actress already joined "The Bonnie Hunt Show", where she revealed her experience of being a mom for the first time. "I can sleep four hours every night now, so, it is just like performing on fumes, a few times," the "Captain America," star said. "Well, it is the best," she said with a smile.

Aside from being parents to their two kids, Smulders has "Results" and "Avengers: Age of Ultron" for 2015, while Killam still stars in "Casual Law" and "Casual Encounters".
