But one thing does remain unanswered -- how did Caitlyn pick her name?
McConaughey popped the question on Christmas Day and posted the photo above to his Twitter account.
As for the wedding, reports are it will take place in Camila’s hometown in Brazil.
A source reveals:
"Camila wants to get married in Brazil with her family all around. She misses the food and the people there, so she's planning a big, beautiful Brazilian wedding.
She's been asking Mateo to put a ring on it forever. She's so happy. It's like a dream!"
Congrats to the happy couple!
