DeAnna Pappas is one proud mom. The former Bachelorette star was positively gushy when she took to Twitter and Instagram on Monday, March 3, to share the first photos of her beautiful baby girl, whom she and husband Stephen Stagliano welcomed on Feb. 6.

"Addison Marie Stagliano, born Feb. 6, 2014. 6 lbs and 6 ounces," she captioned one close-up photo of her newborn daughter swaddled in a pink and white blanket. "My world."

Alongside another shot, this one of Stagliano cradling an angelic-looking Addison against his chest, she wrote, "She owns me." Pappas also shared a picture of herself with the little bundle of joy. "Addison's big day out!" she tagged the sweet snap.

Addison Marie is the Bachelor alum's first child with Stagliano. Her middle name is a tribute to Pappas' mom, who passed away of cancer when Pappas was a child.

Married since 2011, the former reality star and Stagliano first announced their baby news last August. "We cannot wait to make memories with this baby, love it unconditionally, and teach him or her to play soccer," she told Us Weekly at the time. "We have looked forward to this moment for a very long time, and we are so happy to share this exciting news with everyone!"
