The former TOWIE star is currently enjoying a trip across the pond and she managed to bag herself an invite to Charlotte's star-studded 'Make-up Your Destiny' party, held at Nordstrom in The Grove.
And it sounds like Sam had a great time at the lavish event, snapping a pic with Charlotte herself while adding the caption: "Thank you so much for having us .. Such an amazing party launch lots of love xx @ctilburymakeup xxxx #LA."
Of course Sam ensured her make-up was picture-perfect for the occasion, flaunting enviably glowy skin teamed with a pop of coral lipgloss, fluttery lashes and structured yet natural brows.
But Charlotte wasn't the only star Sam managed to hobnob with that evening - she also bumped into Kim Kardashian (and took a quick Insta snap, of course!).
Alongside her photo - which featured a very booby Kim - Sam wrote: "#BFFS @kimkardashian @benny_hancock @ctilburymakeup #charlottetilbury #KimKardashian #KillingIT."
Other celebs attending the event included Kim's mum Kris Jenner US presenter Cat Deeley, model Liberty Ross and 'Air Balloon' singer Lily Allen.
The party celebrated the American launch of Charlotte's beauty range, which is already available to buy in the UK online at charlottetilbury.com and in store at Selfridges.
It's hardly surprising Kim turned out to support the make-up maestro - the pair are good friends after Kim called on Charlotte's services during a trip to London last month.
And Charlotte recently revealed that Kim can't get enough of Supermodel Body, £45, a shimmery firming lotion from her beauty line, which she uses to add a radiant sheen to her pins.
