The Laguna Beach OG clan just reunited for a very special reason: Dieter Schmitz got married!
The former MTV cast member (and notable nice guy) said "I do" to Isabell Hiebl in Monterey, California. Fittingly, Stephen Colletti and Trey Phillips were in the wedding party — and Lauren Conrad was also in attendance.
"Still pinching myself to make sure this is reality," the SoCal native captioned the photograph above with his wife. "What an amazing night. @isathebell Schmitz I love you!"
Before Dieter exchanged vows, Trey posted a sweet snap of all the groomsmen on the "happy day." Looking sharp, fellas, just like you did at the LBHS Prom back in 2004.
Meanwhile, LC couldn't hide her enthusiasm for her newlywed pal — making it a point to show Dieter's brand-new relationship status in Instagram Stories (a screengrab is featured below).
Offer your congrats to Mr. and Mrs. Schmitz in the comments, and check out more photos from Dieter and Isabell's milestone below!
