Whitney Port weds Tim Rosenman in California

Whitney Port is officially married.

The reality star-turned-fashion-designer had plenty of people wondering if she had actually tied the knot last month when she posted an Instagram photo with the caption "Mrs. Rosenman" from her bridal shower.

"When I posted that photo I didn't even think about that. It didn't even cross my mind that people were going to think that I got married," she told CBS News.

But now -- it's official. Port wed her longtime finance, Tim Rosenman in Palm Springs, California - two years after they got engaged, ET confirms. They met on the set of "The Hills" spinoff series, "The City."

"We've been dating for four years, but we've been engaged for two. We kind of took it slow. But gosh, Tim is just the greatest. He makes me laugh harder than anyone can possibly make me laugh. He has such good character," Port gushed to us about Rosenman. "He's all about justice and the difference between right and wrong and he just has really good morals. I know that sounds cheesy. He's a really good communicator, too, and that's always been important to me. I just really need to feel like someone's listening -- like really listening to me. He's just the best."
