The Hills are Alive with the Sound of Wedding Bells: Spencer Pratt, Heidi Montag Engaged

Spencer Pratt has promised to honor, to have and to hold, to love and to cherish a pair of fake boobs for as long as they both shall live.

And if Heidi Montag wants to stick around, too, so be it.

That's right, folks, everyone's least favorite couple is engaged. So, good news, Tameka Foster: you're no longer the most hated fiancee on the planet.

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

According to a source, Pratt purchased the diamond-encrusted platinum band with a pink stone on Monday at Ice at Brentwood Gardens before presenting Montag with a bended-knee proposal. An eyewitness at the store tells Us Magazine: "She was trying on tons of them and they looked really happy!"

Now the pair can plant rumors of a Lauren Conrad sex tape together through old age.

Pratt and Montag have been too busy preening for staged pictures to set a date, but we'll let you know as soon as one is announced. We don't know for sure if Audrina Patridge will be invited, but we can say this with certainty:

Francois-Henri Pinault is no longer the most well-known fiance within the world of celebrity gossip world. Sorry, man.
