Castro’s twin brother, San Antonio Mayor Julian Castro (D) broke the wedding bell news in a Monday Facebook post, writing, “Congratulations to my brother, Joaquin Castro, and Anna Flores on their engagement! They've been together three years and have been great friends for five. May they have a blessed future together!”

The House member’s office didn’t immediately respond to ITK’s request for comment.

A March Vogue profile of the political siblings declared, “The only reliable way to tell which Castro you’re speaking to is by checking for a wedding ring: Julian is married.” 

Julian Castro told the glossy mag at the time he was waiting for his one-minute younger brother to tie the knot, saying, “I’m really looking forward to Joaquin getting married, when he has kids.”

UPDATE (12:15 p.m.): Rep. Castro said in a statement to ITK, “Anna and I are so grateful for the outpouring of love and well wishes on our recent engagement. We don’t have a set date, but we are excited for the many years together to come.”
