The Grimm star took to Instagram.com to share the news that she had given birth, and showed off a cute picture of her cradling her son.

She added the caption, "GRIMM Season Finale! @christhile & I had a baby! I DON'T KNOW WHAT'S MORE INTENSE!! JK, it's definitely childbirth, but watch tonight anyway! #buryingthelead @nbcgrimm"

The couple announced the good news in March (15) and Coffee told People Magazine they struggled to settle on a baby name, saying, "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."

Coffee and Thile tied the knot in 2013.
