And, after catching up on lots of cuddles and kisses, the former TOWIE star shared a heartbreakingly cute photo of her sister Billie's baby.
The incredibly photogenic child can be seen slouched in a miniature Mickey Mouse chair - pink, of course! - and her baby blue eyes are focused on the camera.
Billie and fiancé Greg Shepherd's daughter, born on 10 July, looks the spitting image of her handsome daddy in the photo.
Alongside the snap, proud auntie wrote: "Have had such an amazing time but so excited to see my little lady.. She's grown in the week I have been gone #baby #niece #nelly #love xxx."
CBB star Sam, 23, also shared some photos of her break in California, including a sunny shot of lunch at Nobu in Malibu.
While in LA, Sam visited the Playboy Mansion, partied with Kim Kardashian and enjoyed a spot of sightseeing.
Sam - who is Reveal's fashion and beauty columnist - has been tight-lipped about the reason for her trip, but we can't help wondering if it's an exciting career move!?
