When we left off, Spencer and Heidi finally tied the knot and Lauren made one of her last appearances when she showed up at the wedding. Kristin Cavallri, a Laguna Beach veteran, was the surprise guest and began to shake things up. And Audrina and Justin Bobby officially broke it off.

On tonight’s episode of The Hills, Lo, Audrina and Stephanie prepare for Heidi and Spencer’s Welcome Back Party and for Kristin to join their circle. Not only is she Brody’s ex-girlfriend, but also she has been known since her days on Laguna Beach as a man-eater, a true female player. Lo warned newly single Audrina to watch out because she might just swoop up her ex, Justin.

Spencer and Heidi were ecstatic that they could finally invite all their friends to their party without worrying about who had a problem with whom, but they were so wrong. That afternoon at their rooftop poolside bash Kristin arrived at the party and did not even greet Lo, Stephanie or Audrina. She was instantly drawn to Justin Bobby and began talking to him. Stephanie came up to them to defend Audrina telling her to step off. From there it turned into a frenzy of pointing fingers and yelling, which ended with Kristin screaming, “It’s on bitch,” before finally walking away.

Audrina felt Kristin was violating girl code by talking to Justin and decides that any means of a friendship between her and Kristin is officially over. But Lo and Stephanie are even more worried about what will happen at Frankie’s birthday party the next day; they are afraid she will turn their lives upside down.

Meanwhile, Speidi go house hunting and visit an adorable start-up house in the suburbs, which Heidi loves. But what she is most excited to see is the nursery, but Spencer is completely disinterested in looking at any room devoted to babies.

At Frankie’s birthday party Kristin begins flirting with Justin. The flirting escalates when the group leaves the party to go watch the Lakers game at a bar. Justin chooses to sit with Kristin and when someone takes her seat, she sits in his lap. Kristin asks to take a ride on Justin’s motorcycle and implies that he take her out on a date.

Speidi continue house hunting and visit an ultra-modern party house in Hollywood. Heidi doesn’t like it and would really like to live in a cozy house in the suburbs complete with a white-picket fence. But she won’t be getting that, because Spencer has already put the deposit down on the house and they will be renting it out until the end of the year. Heidi is upset that even as a married couple Spencer does not include her in his decisions.

Lo and Stephanie fill Audrina in on all that happened at Frankie’s party and at the bar. The girls don’t like how entitled Kristin feels to do whatever she wants and date Audrina’s leftovers.

Later, Kristin meets Justin for dinner. She told him that she thought twice about coming because she could see that Audrina still had feelings for him. Justin explains that they were never exclusive, but as a girl Kristin sees it. Even though she understands Audrina’s feelings, she doesn’t stop the flirtation. Kristin tells Justin about her great organization skills, her beautiful apartment and her bed very comfy. Was an invitation to come home with her, buried in there? We’ll see.
