Stars of the MTV series The Hills Spencer Pratt, Heidi Montag, Whitney Port, Audrina Patridge, and Lauren Conrad pose as they arrive at the MTV Movie Awards in Los Angeles, Calif. Sunday, June 3, 2007.

Heidi Montag and Pratt are engaged, US Magazine reported Wednesday, adding he proposed to her Tuesday night at the Bacara Resort & Spa in Santa Barbara.

“She said, ‘yes.’ She’s over the moon!” a “source” told US.

The Hills’ second season finale ended with Montag moving out of the apartment she shared with Conrad to instead live with Pratt — which apparently disrupted the ladies’ friendship, as Montag reportedly declined to attend The Hills: Finale After Party at MTV Studios in New York City because Pratt was not invited.

“Lauren is just jealous of Heidi’s relationship with me,” said Pratt in the May 14 issue of In Touch Weekly. “Until she accepts Heidi being with who she loves, their friendship is not going to work… Lauren’s the one who wanted to date me first, before Heidi. [Conrad] wishes she was in love.”

The loss of Conrad and addition of Pratt in her life aren’t the only major changes for Montag, as she reportedly underwent breast augmentation surgery on April 2 at the Beverly Hills office of plastic surgeon Dr. Frank Ryan, a procedure she had been pondering for several years. Whether it led to Pratt popping the question earlier than he planned remains to be seen — the couple has been dating for only eight months, but the two have been spending a good amount of time frolicking at Los Angeles beaches in recent weeks.

“We have so much fun,” said Montag in the May 21 issue of OK! Weekly. “I never knew I could love someone like this.”

Montag, 20, and Pratt, 23, have yet to set a wedding date, according to Us.

“I’m having fun with Spencer, and we’re looking forward to a fun summer,” said Montag in the May 28 issue of Us.

The Hills star Heidi Montag shows off her newly sculpted schnoz and boob job to boot at the beach on Thursday in Los Angeles, accompanied by live-in boyfriend Spencer Pratt.

The reality TV pair played a game of paddle ball and showed off their affection for each another in more ways than one — they kissed, they cuddled, they shot water guns at each other, they chased each other in the water, he did push-ups with her sitting on top of him, he carried her on his shoulders and he even slathered sunscreen on her. Whew.

Newly buxom blonde Heidi Montag, 20, donned a bikini and her new golden globes on a beach in Malibu beach while out with boyfriend Spencer Pratt on Sunday.

The Hills star had a boob job just three weeks ago, reports reports Us Weekly. Recovery from plastic surgery sure is quick these days!

What do you think of Heidi’s plastic surgery? YAY or NAY?
