Lauren Conrad is ''so proud'' of her fiancé for graduating from law school.

The former 'The Hills' star, who is set to marry William Tell, 34, this summer, was on hand to watch him collect his post-graduate degree from the University of Southern California in Los Angeles on Friday (16.05.14).

The 28-year-old fashion designer shared a photograph of herself with William in his red graduation robe and matching cap on Instagram, with the caption: ''This guy graduated from law school today! So proud! #esquire''

The couple - who recently got a puppy together - got engaged in October and William previously gushed about how supportive his famous fiancée was while he completed his education.

He told the legal site Above the Law in January: ''She's extremely supportive of me being in law school, which is funny because I mostly come home and want to forget about it or to talk about what I'm doing at work. She's definitely interested in what I'm doing at school though. And it comes up at weird times. Like, a while ago, we were watching [legal drama] 'Suits,' and I remember saying that what was happening in the show wasn't exactly the way it worked in real life.''

The couple plan to relocate to their native Orange County, California for the summer so William can study for his upcoming Bar exam.
