Ten Times 'Vanderpump Rules' Star Brittany Cartwright Stunned On Instagram

Brittany Cartwright had a rollercoaster year, but she's headed for a fairytale ending. The 29-year-old Vanderpump Rules star is in wedding planning mode for her upcoming nuptials to longtime love Jax Taylor, and she's more fit and fabulous than ever.

Cartwright and Taylor went through a slump last year, but she supported her man through his personal struggles. After Jax popped the question at the Malibu eatery Neptune's Net in June (fans will see the proposal play out next season on Vanderpump Rules), Cartwright kicked it into high gear with wedding planning and a stunning weight loss. The Kentucky beauty recently revealed that she's lost a whopping 25 pounds, telling E News! that her main focus is to be "happy and healthy."

"Being healthy and fit makes me feel so much more confident and happy with myself," Cartwright told E! "It feels really great when you start seeing results and your old clothes start to fit again."

Not to mention bathing suits. Cartwright is a prolific Instagrammer and her feed is populated with gorgeous glam shots and bikini snaps that show off her fit and toned bod. Can you imagine what this Vanderpump beauty will look like in a wedding dress?
