More than you'll ever know. That's how much it hurts that I give a shit about this. And yet it is with great shame that I pass on the news of Heidi and Spencers engagement.

Usmagazine.com has learned exclusively that Spencer Pratt and Heidi Montag are engaged!

Pratt, 23, popped the question to Montag, 20, Tuesday night at the Bacara Resort & Spa in Santa Barbara, says a source who adds: "She said 'yes.' She's over the moon!"

The Hills stars, whose controversial courtship was chronicled last season on the hit MTV reality series, have been dating for just eight months.
