Christina Perri is pregnant!

The “Jar of Hearts” singer announced she and fiancé Paul Costabile are expecting their first child together in a sweet post shared to Instagram on Saturday. The black and white snapshot sees Perri and her 3-year-old niece Tesla holding her baby bump with a message that read, “Tesla’s little cousin is coming soon.”

“Guess what?” the singer-songwriter included in her caption. “Paul asked me to marry him tonight and i said yes!” she shared alongside a photo of her new piece of bling

It’s been quite an exciting time for Christina, who in late June announced she and Costabile were engaged.

Her TV personality husband-to-be also dedicated a romantic note to the “A Thousand Years” singer following the proposal. “I knew I wanted to ask this girl to marry me the day she walked into the green screen for an interview almost 4 years ago,” he shared. “I finally asked her right here tonight and she said yes !!!”

Costabile has yet to comment publicly on Christina’s pregnancy.
