The TOWIE star was one of the famous faces helping out at the Hopefield Animal Sanctuary summer fete in Brentwood, Essex on Sunday (21 July).
Lauren joined TOWIE co-stars including Samanatha Faiers and Charlie King, and Hopefield's patron and trustee Leona Lewis, for a day of fun in the sunshine.
Looking gorgeous in a simple monochrome outfit, the DJ helped out on the cake stalls and got to know some of the creatures being cared for at the sanctuary.
And while plenty of us probably wouldn't want a lizard crawling over our shoulder, Lauren was all smiles as she made friends with the tiny reptile above.
She tweeted: "Made a new friend today at Hopefield Animal Sanctuary."
Hopefield provides a home for animals that are sick, abused or neglected, and yesterday's star-studded event also marked the non-profit organisation's 30th anniversary.
