Lauren Conrad to Appear on The Hills Reunion

Lauren Conrad is finally returning to The Hills ... right after it ends.

One week from tonight, the girl who made the MTV reality show a hit will be on hand for the Live Reunion Show after the now-sagging series mercifully goes off the air.

The reunion will immediately follow the series finale of The Hills and the season finale of The City. Whitney Port reported the LC news, as well as her own attendance:

"I am so happy to tell you all that I will be attending the reunion, as will Lauren!" Whitney wrote on her official site. "I am so excited to see everyone and catch up."

"I am so excited to see what's next for them," the former Hills star and current City leading lady continued. "It's been so long since we have all been together."

REUNITED: For one night and one night only, next Tuesday.

What remains unclear is whether Heidi Montag and Spencer Pratt, exiled from the show in recent weeks without notice, will appear between now and July 13.

The gruesome twosome was featured prominently in the first part of this season, but then Spencer went haywire, they supposedly broke up in real life, etc.

It's not clear why, but there has been no explanation of their vanishing from the series. Tonight, the penultimate episode of The Hills airs, followed by The City.

The former will likely focus on Kristin and Audrina's predictably boring romantic drama. Sigh. We can only hope Speidi returns to liven things up one last time.
