Jason Sudeikis Beams While Showing Dianna Agron Pics of Newborn Baby Otis!

Jason Sudeikis holds up his phone to show his co-star Dianna Agron pictures of his newborn son Otis Alexander on the set of Tumbledown on Thursday (April 24) in Boston, Mass.

The 38-year-old actor was beaming as he showed off his new little guy – so adorable!

Jason and his fiancee Olivia Wilde welcomed baby Otis earlier this week, and even released the first picture of him!

“If Otis was on Cribs, his crib would win. I wish I could fit in it. Thanks, @SerenaandLily for the lovely gifts. Do you make adult swaddles?” Olivia tweeted the next day about her newborn.
