They've only been dating for a few months now, but Stephanie has already declared her love for her new beau, and since getting together the pair have been inseparable.
But, while Steph has been cosying up to Josh's family here in London, it seems the MIC newcomer is already a big hit with hers out in LA.
While we know Josh has already met Stephanie's mum Janet, we don't think he has come face-to-face with her brother Spencer Pratt and his wife Heidi.
But, helping to get rid of any pre meet-the-family nerves, Steph's sister-in-law has already accepted the Chelsea boy with open arms.
Taking to Twitter last night, The Hills star tweeted: "So thankful @stephaniepratt has met the love of her life @joshshepherd88 ! It's different to love someone and be in love with someone!"
Love of her life?! Sounds like Steph and Josh are more serious than we thought!
On seeing Heidi's tweet, Stephanie retweeted her message, while Josh revealed he will be heading to LA to see Steph and her family after Christmas, replying: "See you in January!"
Stephanie and Josh's love affair began after the US beauty officially moved to London and returned to Made In Chelsea.
Things for the couple didn't start off too well as Steph's former flame Stevie Johnson wasn't too happy with his pal dating his ex.
Despite Stevie telling Josh they couldn't be close friends if he dated Steph, the couple continued to see each other anyway and are now happily loved-up.
And, since then, Stephanie has claimed her current squeeze has made her the "happiest girl in the world".
Earlier this month, while wishing Josh a happy birthday, Steph tweeted: "Happy birthday to the sweetest man I've ever known- I love u so much @joshshepherd88!!!! Thank you for making me the happiest girl in the world."
