Heidi Montag, Spencer Pratt Attend Hills Co-Star Jen Bunney's Wedding

A sort of Hills reunion occurred at the weekend, as Heidi Montag and Spencer Pratt attended Jen Bunney's wedding.

The reality TV couple have surprisingly stayed in touch with Bunney, who first starred in Laguna Beach and then later the Hills, as they celebrated her union to Taylor Dunphy in California.

Heidi showed off some photo booth snaps of her and her hubby enjoying Jen and Taylor's big day, as well as a cute snap of the happy couple.

The blushing bride wore a stunning ivory strapless gown with her long brunette tresses in loose waves, with her new husband in a fitted black tux. 

It's not known whether fellow Hills alumni Lauren Conrad attended, the two were childhood best friends before living out their friendship on the big screen.
