The 15 people who watched the third season of Laguna Beach surely remember Lauren Conrad's awkward younger sister, Breanna Conrad.

What many of you may not be aware of is that Lauren and Breanna also have a younger (cute!) brother by the name of Brandon Conrad!

Lauren Conrad hung with Brandon at The Lauren Conrad Homecoming Fashion Show at Irvine Spectrum Center on Monday in Los Angeles.

Lauren's parents, Jim and Kathy Conrad, as well as LC's much-maligned BFF, Lauren “Lo” Bosworth, were also present at the event.

The Hills star and Orange County native kicked off the first-ever Style Week Orange County with the unveiling of her holiday collection.
