And baby makes three!

Grimm star Claire Coffee has welcomed her first child — a baby boy — with her husband, musician Chris Thile.

“GRIMM Season Finale! @christhile & I had a baby! I DON’T KNOW WHAT’S MORE INTENSE!!” she Instagrammed Friday evening. “JK, it’s definitely childbirth, but watch tonight anyway! #buryingthelead”

Son Calvin Eugene Thile — whose middle name is in honor of Coffee’s late grandfather — was born Monday, May 11 in Portland, Oregon, Coffee’s rep confirms to PEOPLE exclusively.

“Cal has already made great strides in the arts of eating, sleeping, and pooping,” the couple tell PEOPLE. “We are heads over heels in love.​”

Days before she debuted her bump at a SAG Awards party in January, Coffee, 35, confirmed she was pregnant.

“I’m not a patient person and I didn’t realize you had to wait 10 minutes for the double lines to show up on those little pregnancy tests,” the actress told PEOPLE. “Later, I was taking out the garbage and I saw these little pink double lines in the trash.”

In March, the mom-to-be revealed she and the Punch Brothers member were expecting a baby boy — and having a hard time deciding on his name.

“We’ve been having trouble finding names that we both like that are acceptable with the last name of Thile because my husband doesn’t want it to be too cutesy,” the actress told PEOPLE.

But, despite the struggle, Coffee couldn’t be happier with her firstborn being a boy.

“It meant that my husband would be the one tasked with doling out puberty advice. I was also immediately excited about the baby bow tie possibilities,” she told Mini Magazine.

And the thing is, Erin…you really are the only one that matters, and yours is the only opinion that matters, as well. It’s a shame they didn’t check with you before writing bout someone you don’t know, but jillions of others do! Why are some of you so egotistical?
