Tony Romo is off the market – and it appears he couldn’t be happier.
The Dallas Cowboys quarterback, 31, said “I do” to Chace Crawford’s sister Candice, 24, on Saturday at Arlington Hall in Dallas in front of approximately 600 guests.
“It was perfect,” a source told PEOPLE about the elegant affair. “From the ceremony … to a vibrant after-party and great music selected by Tony himself.”
Attendees, including Miles Austin and Troy Aikman, looked on at the grinning bride and groom, who both wore white.
The couple, engaged since December, first started dating in 2009.
