The MTV reality show crew threw together a rather impressive shoot for the season finale of The Hills (Heidi and Spencer’s sappy fake wedding). Over 200 guests showed up at the Westminster Presbyterian Church today for the publicity event.

A skywriter was hired to write “Spencer Loves Heidi” in the sky before the event. Guests present at the ceremony included many cast members from The Hills, Heidi’s sister Holly, Spencer’s sister Stephanie, and even Heidi’s mother, father, and both of her step parents. As we previously reported, Lauren Conrad showed up as well for her big scripted reconciliation with Heidi.

Heidi wore a $19,000 Monique Lhuillier dress, and $1.2 million worth of Neil Lane jewelry for the ceremony.
