We couldn't be more thrilled about Molly and Jason Mesnick's new baby, the adorable bundle of joy commonly known as Riley Anne. This hot couple from The Bachelor Season 13 popped out the newest addition to their family on March 14, 2013, and she's already made the first of many milestones. That's right, this beautiful bambino just flashed her first toothless grin!

"Little Miss Riley is starting to smile!" Molly proudly tweeted on April 16. "That face is heaven on earth!"

Um, it's called Instagram, Molly. Pics or it didn't happen. In other news, some fans are concerned that Baby Riley's big brother, 8-year-old Ty (aka Jason's son from a previous relationship), might be jealous of all the love and attention his little sister is getting. The verdict? As if!

"not at all!" Molly tweeted in response to a fan. "He LOVES her! He's a great big brother!"

We're thrilled that Ty and Riley are already bonding all over the place, but seriously, Molly and Jason. Learn how to use a camera like normal reality TV stars. We're dying to see pictures of your kiddos!
