The 28-year-old fashion designer, who found fame via MTV's 'Laguna Beach' and its spin-off 'The Hills', had been engaged since October 2013, reported E!Online.
This is the first marriage for the bride and the groom, 34, who both hail from Orange County.
Conrad was introduced to Tell via mutual friends on Valentine's Day in 2012.
The day before her wedding, Conrad hinted she would be walking down the aisle.
"I'm pretty excited about the weekend ahead. I have a feeling it's going to be a good one," she had said.
