2014 Is the Year of Hot First-Time Dads in Hollywood

In May, proud dad John Krasinski shared a picture of his daughter, Hazel. He and Emily Blunt welcomed their first child in February, and a few months later, he tweeted, "I'm thrilled to introduce you guys to Hazel!!!"

Mila Kunis gave birth to a baby girl in early October, and new dad Ashton Kutcher shared the news on his website, saying, "Mila and I would like to welcome Wyatt Isabelle Kutcher to the world. May your life be filled with wonder, love, laughter, health, happiness, curiosity, and privacy."

Ryan Gosling and Eva Mendes welcomed their baby girl in September, and the couple's news led to quite a few crazy Internet reactions about Ryan becoming a dad. (A very, very hot dad, that is.)

Jason Sudeikis became a first-time dad in April, when Olivia Wilde gave birth to their son. The actress hilariously tweeted, "Ladies and gentlemen, Otis Alexander Sudeikis has LEFT the building! (I'm the building)."

Once Upon a Time costars Ginnifer Goodwin and Josh Dallas welcomed a baby boy named Oliver in June. The pair got engaged in October 2013, and in September, Ginnifer gushed about Josh being an awesome dad, saying, "He's my knight in shining armor."

Justin Bartha and Lia Smith tied the knot in January, and they welcomed their first child together, a girl named Asa Charlotte, in April.

Although he isn't a dad just yet, Hayden Christensen and Rachel Bilson are expecting their first child together, reportedly a girl, and they celebrated their upcoming arrival with a baby shower in September.
