Jessica Simpson showed off her slim, svelte summer physique while boarding and deboarding a coast-to-coast flight from New York-to-Los Angeles Wednesday.

She’s sexy and she knows it: The 33-year-old’s smile says it all as she passes through JFK airport.

Simpson relishes her model form, arguably the most glam and in shape we’ve seen her in a decade.

The Weight Watchers poster girl, a source told us, has caught the attention of Kim Kardashian, who is jealous of the slim, lean form she’s been able to achieve.

The Dukes of Hazzard star’s “latest triumphant pictures show that she’s achieved a streamlined shape that has Kim in tears of envy.”

Simpson exudes poshness and class in the dark blue dress and white heels.

The Employee of the Month star flashes her amazing smile as she passes through customs.

Simpson is purportedly ready to tie the knot with her fiancé of four years, former 49ers tight end Eric Johnson.

The Fashion Star was decidedly more dressed down in a sheer, baggy get-up as she touched down in LAX.

The Blonde Ambition beauty opted for comfort over the photo op as she ventured into the West Coast.

The “I Wanna Love You Forever” singer has been honing her figure with a strict diet-and-exercise regimen as of late.

Simpson runs as many as six miles a day in her training, according to reports.

The "With You" singer has gained the shapely form under the tutelage of her longtime trainer, Harley Pasternak.

Simpson is brimming with more confidence than she’s had in years, according to reports.

Simpson’s placated by a strong family life and steady career, allowing her to focus on her fitness.

Simpson, at one point, tipped the scales at more than 210 pounds.
