CW Stars Jensen Ackles and Danneel Harris Tie the Knot

It’s a match made in CW heaven.

Supernatural star Jensen Ackles and longtime girlfriend, One Tree Hill actress Danneel Harris, got married Saturday in Dallas.

“I’ve never seen a more stunning bride,” a wedding guest tells PEOPLE, “and the couple looked happier than ever.”

Ackles, 32, and Harris, 31, who dated for three years and costarred in the 2007 romantic comedy Ten Inch Hero, announced their engagement in November.

“Ultimately [I] want someone who you can pal around with and also be intimate with,” Ackles told PEOPLE in 2006 about what he looks for in a woman. “Someone who can laugh at your jokes. It may sound cheesy, but someone who can be your best friend as well as your love.”
