The TOWIE star was all smiles as she helped out at the Hopefield Animal Sanctuary Summer Fete in Brentwood, Essex on Sunday (21 July).
Sam dressed for the hot temperatures in a pretty patterned dress teamed with wedges.
She tweeted before arriving: "Looking forward to attending the @leonalewismusic event tomorrow at @Hopefield_Essex - a great cause x."
The Hopefield Animal Sanctuary is a non-profit organisation that provides a safe haven for around 200 sick, abused and neglected animals. It currently houses a variety of animals, including horses, goats, sheep, pigs, chicken, cats and donkeys.
Sam worked alongside Leona Lewis, who is a trustee and patron of Hopefield, at the event, which also attracted support from Lauren Pope, Jeff Brazier and Alex Reid.
Yesterday's event celebrated Hopefield's 30th birthday and featured festival favourites including face painting, raffles, and Pimms. Celebrities manned some of the stalls, while Leona was in the animal adoption tent.
TOWIE wrapped for the season earlier this month, but Sam has been keeping busy with work, including her Minnies Boutique store in Essex.
She's currently gearing up for another Minnies pop-up event, this time in Manchester's Corn Exchange on 17 August. Sam and sister Billie have been taking their store on a popup tour of the UK in recent months, attracting hundreds of fans in each city.
