The 41-year-old star, famous for his roles in shows such as Pretty Little Liars and The Flash, announced the happy news on Facebook on Friday (03Mar17), alongside a sweet photo of their new addition, who arrived on Wednesday (01Mar17).

In the snap on social media, Nicholas commented that it was the "best day of his life", and is seen softly cradling his wife Kelsey Crane-Gonzalez and their baby daughter, Ever Lee Wilde Gonzalez. The couple released more details of their daughter's arrival to People, including an adorable picture of the newborn cuddled up in white blankets.

“We are looking forward to sleepless nights and blissed-out days. We are so in love with our new, little person. She is the best thing - ever!” Nicholas and his wife said in the statement, adding that their baby daughter weighed 8 pounds, 1 ounce upon arrival.

The couple announced in September (16) that they were expecting their first child together, with Kelsey apparently due in February (17). “We are over the moon and we can’t wait to meet our little person,” she told at the time. She also revealed the pair did not find out the sex of their baby prior to her giving birth.

Ever's arrival comes after Nicholas and Kelsey married in front of family and friends, including Jane the Virgin star Gina Rodriguez and How to Get Away with Murder's Charlie Weber, in Los Angeles in April last year (16).

After the ceremony, the couple told People they were excited to have children, with Nicholas saying: "It's all about building a family. We're ready and excited!"
