This is so exciting!

Gwen Stefani and Blake Shelton are "determined to have a child together," so they've turned to surrogacy to make their dreams come true!

"They are in the final stages of choosing the woman who will carry their baby. It’s extremely important to Gwen that she give Blake a biological child, and Blake is so excited,” a source tells Us Weekly, noting that even though Shelton is grateful for Stefani’s sons, “he wants his own child too.”

The No Doubt songstress and the country crooner began dating in 2015 after their respective splits from Gavin Rossdale and Miranda Lambert, and they're been inseparable ever since.

“Gwen just is so in awe of the love Blake has, not only for her but for the boys,” the source added.

We'd die if they had a girl!
