Just the other day we were waxing poetic about the oodles of babies Survivor stars seem to be having and now we’ve got another name to add to the “just arrived” list! Welcome to the world, Adelina Rose Mariano!

If her last name didn’t give it away, Little Adelina is the child of Survivor star Rob Mariano and his former castmate and now wife Amber Mariano. She’s Baby No. 4 for the couple, who have three daughters together: Lucia Rose, born July 2009; Carina Rose, born December 2010; and Isabetta Rose, born May 2012.

Notice a theme in those middle names? Yep, Rob and Amber have themselves quite the bouquet of roses.

Boston Rob shared an adorable photo of his little ones greeting their family’s latest addition. “Lucia Rose, Carina Rose, and Isabetta Rose are beyond excited to welcome their new sister Adelina Rose!” he tweeted June 20 alongside a too-cute-for-words snapshot of the trio peering in at the littlest Mariano!

The Survivor champion also shared a photo of himself and Amber holding their crying bundle of joy, who arrived on June 20. “Mom and baby are doing great! #4for4,” Boston Rob wrote, using the best hashtag we’ve seen today.

Congratulations to the whole Mariano family!
