A few years ago, millions of viewers anxiously tuned in to catch an infamous MTV screaming match at then-Hollywood hot spot Les Deux that forever changed the relationship between best friends – and The Hills reality starlets – Lauren Conrad and Heidi Pratt.
Fast-forward to the present, Heidi (née Montag), 27, says the night that made “You know what you did” a household phrase is now water under the bridge.
“I’ve talked to [Lauren] a few times on the phone and we’ve caught up,” Heidi told PEOPLE on Friday. “She’s been really sweet. The last time we talked was like a year ago. I lost her number so I haven’t been able to call her [recently]. I told her I got really caught up and I was sorry about how things happened. I told her I miss her and she told me she’d always be there for me.”
Heidi, who wishes her ex-BFF a “blissful” engagement, acknowledges that the two won’t necessarily always be “friends,” but they’ll “always have a special place” in each other’s hearts.
“We’ve been through a lot and we have a relationship that only the two of us would understand,” Heidi explains. “She was my best friend for a long time.”
Spencer Makes Peace
The TV personality’s husband, Spencer Pratt, also lost a dear friend while caught up in the mix of reality television.
“I turned on him for just being the nice guy that he is,” Spencer, 30, told PEOPLE, of childhood pal Brody Jenner, who briefly dated nemesis Conrad. “I wish I’d handled that differently. I abandoned him and our friendship and we were such best friends. I got caught up in ‘my character.’ Thankfully he has such a forgiving heart and we’re back to being great friends. He’s always been there for me.”
Their closest comrades aren’t the only ones the happily married couple have made peace with, post-Hills.
