The girls got together to celebrate Lauren's latest fair trade business venture, The Little Market, at a concept store in West Hollywood and appeared to be as close as they were on the hit MTV show as they posed for a cute photo.
Stephanie showed her support for Lauren and her new organisation by tweeting a snap of the pair together, writing: "My friends have the biggest hearts!! Congrats on @thelilmarket @laurenconrad @HannahSkvarla !! Xxx,"
In the photo, 27-year-old Lauren is seen looking glam in a black blazer and with a perfectly coiffed glossy mane.
Meanwhile, Stephanie looks cool in a pair of ripped jeans and a black vest top, as she stands in between LC and her business partner Hannah.
The Hills went off air in 2010, although Lauren left the show in 2009 following a surprise appearance at the wedding of Heidi Montag and Stephanie's brother Spencer.
Stephanie was originally brought onto the show as an on-screen rival for Lauren, but the girls surprisingly hit it off and eventually became good friends.
And it seems like they've kept in touch since going their separate ways, which we love to see!
Although Lauren - who recently got engaged to boyfriend William Tell - has left her reality television days behind, Stephanie has swapped the cameras in the States for an appearance in our very own Made In Chelsea.
The blonde Californian filmed a few special episodes of the E4 show during her time in London over the summer, while she was dating Chelsea Lothario Spencer Matthews.
