Despite not getting off to the best start back in the day (thanks to clashing over Spencer Pratt!), Stephanie and Lauren proved they have remained close friends since starring on The Hills together.
And meeting for a long overdue catch up, the girls were all smiles as they celebrated their friend's pregnancy.
Attending her pal Hannah baby shower, it's unsurprising Stephanie was joined by Lauren, as Hannah is the co-founder of her Little Market website.
Sharing a snap from their reunion, a super-excited Stephanie told fans: "Can't wait to be an auntieeee! @hannahskvarla @laurenconrad."
In the photo, Hannah is dressed in a cute pink dress showing off her very big baby bump while Stephanie and Lauren are cuddling up to her. Cute!
And we've no doubt Steph was excited to see her friends again, as last year she permanently moved to London following her time on Made In Chelsea.
Over Christmas, the blonde beauty jetted back to LA to spend the festive season with her family and visit her BFFs - and we reckon she's had plenty to catch up on.
Since Steph set up home across the pond, she began dating her co-star Josh Shepherd and the pair are now seriously loved-up.
The reality star has already been seen declaring her love for Josh over social media, and during the finale of Made In Chelsea, her boyfriend revealed the pair are now moving in together.
Meanwhile, Lauren has wed her long term partner, lawyer William Tell.
In September, she and William tied the knot in front of those "they love the most" in an intimate ceremony in California.
Following their nuptials, the pair then jetted off on honeymoon to Italy to celebrate.
While Steph wasn't in attendance at her pal's wedding, she did send Lauren her well wishes tweeting: "Hello Mrs Tell Xoxoxoxo."
