The 33-year-old designer met Rangel, who is also the chief financial officer of Wu's label, on New Year's Eve, 2005.

"This weekend I celebrated one of the happiest days of my life," Wu wrote on Instagram alongside an image of the pair walking up the aisle.

"I got married to @tavonyc and I feel like the luckiest person in the world. I am so grateful for my amazing friends who joined us on this special day @hotelesencia but most of all to my parents, Hank and Jennifer and my brother and sister Kevin and Migumi for being the most loving, supportive, and special people in my life.
