A heartwarming moment from an unsuspecting dad brought his family to tears.

Angel Trevino and her 11-year-old daughter, HaLeigh, secretly went about changing the girl's last name to the same as her adopted dad.

On Feb. 1, they sat David down and made him read out a letter explaining the whole thing.

"You stole her heart from day one, but she stole your last name forever," was just one of the lines that brought tears to David's eyes.
