The former Hills star beamed from ear to ear while attending the Veuve Clicquot Polo Classic event in LA, showcasing her impeccable sense of style in the process.
While many A-listers opt for fancy frocks for such lavish occasions, Lauren looked cute as a button in a pretty silk blouse adorned with a colourful poppy print.
The blonde beauty tucked her top into a high-waisted navy blue miniskirt, which left her sunkissed pins on full display, completing her look with strappy nude sandals.
Lauren wore her glossy golden locks draped over her shoulders in a bouncy blow-dry and she flaunted a berry purple pedicure teamed with a coral pink mani, finishing her beauty look with her trademark flick of liquid liner and glossy apricot lips.
And the starlet ensured we all got a glimpse of her sparkling engagement ring and wedding band by resting her left hand on her hip as she posed up a storm for photographers.
Lauren married lawyer William Tell in an intimate ceremony in California last month (13 September) after William popped the question back in October 2013.
Loved-up Lauren and William then jetted off on a romantic honeymoon in Italy to enjoy newlywed bliss, where they indulged in a tasty post-wedding diet of pizza and red wine.
Sounds like our kind of holiday!
