IMAGES: The Top 25 Women's Beach Bodies 2012!

Women's Health Magazine has released its annual list of the sexiest summer bodies featuring female celebs for this year. Take a look!

It's bikini season and Women's Health is looking to inspire you to get into shape.

The magazine has just released its yearly 'Best Summer Bodies' list of femme fatales and partner publication Men's Health has done the same (click here for a look at the men's list).

In the following pages, we bring you the models and actresses who've made an impact in 2012!

1. Julianne Hough

The 23-year-old American dancer/singer/actress topped the list. Julianne hates gymming, but dancing up a storm and keeping an eye on her diet does the trick.

The Sports Illustrated and Victoria's Secret supermodel made it to second place. Thirty three-year-old Marissa is one of the sexiest women in the world alright.

The star of hit musical series Glee Lea may be petite, but she has the toned look of an athlete. She's known to be a fan of Bikram yoga.

Dancer, model, TV personality -- and definitely a knockout! At 40, Brooke is still sizzling and she's even released her own workout DVD.

Musician and actress Katharine used to suffer from an eating disorder, but she's beaten it and at 28 is in the best shape of her life. She nabs fifth place.

Justin Beiber's girlfriend is a hottie and at 19, she's beginning to cultivate quite a grown-up image with bikini pics!

The O.C. actress Rachel looks right at home in a two piece and enters the Women's Health round-up at Number Seven.

Well, she certainly has a wild bikini bod! Brunette beauty Olivia, 28, takes eighth place.

She's a mother and 42, but Gwen still has the best abs in the business. The musician-cum-fashion designer has an intense workout regime that comprises weightlifting, boxing and cardio -- plus, she eats only organic foods as far as possible.

Another mommy who makes the list is golden-haired stunner Kate. Five small meals a day, Pilates and dancing keep her in top form.

American actress Kristen, 31, falls just short of the top 10 -- but her body certainly deserves a perfect score.

The Gossip Girl star also joins the ranks, coming in at Number 26 thanks to her remarkable curves.

The Israeli supermodel took Maxim's Hottest Woman in the World 2012 title last week, but didn't do all that great in the Women's Health Summer Bodies size-up.

German stunner Diane is up next at 14 -- her seductive blonde appeal rates as high as her figure, which you can put down to her former ballet training, love of the outdoors and healthy diet.

Yummy mummy Jessica is all for a natural, healthy lifestyle and sets an example by way of her own wholesome appeal.

Gwyneth's beauty and fitness suggestions, shared in her lifestyle newsletter GOOP!, are often mocked in the media. But she seems to figure on every hot-list that matters, including this one!

With her legendary curves and bold attitude, the Barbadian pop princess comes in at 17. RiRi is so committed to her fitness levels, she is sometimes known to work out even at 2 am!

The TV host and dancer, 33, stays fit by rocking it out to great music. It's the fastest way to a killer shape and lots of fun too, so you may want to take a leaf out of her book and follow suit.

Cam's a self-confessed tomboy. She works out, does cardio, weight-training, is a surfing fanatic...so it hardly surprises anyone that Women's Health thinks she deserves a mention on the list.

The High School Musical starlet is a regular gym bunny, so not only is she in fantastic form, she's also always sporting a healthy glow.

Bootylicious JLo seems to have discovered the fountain of youth. In her 40s and a mother of twins, she's still one of the sexiest sirens on the planet!

Is it just us or is the 40s club dominating when it comes to best summer bods? The super-hot A-lister follows Jennifer in at 22.

The former Pussycat Dolls band member has gone solo and is getting noticed bigtime. While she's a great singer, there's no ignoring her exotic looks and fabulous figure either!

Raven-haired and ravishing Olivia, 31, narrowly avoids last position -- her jaw-dropping curves see her to 24.

And rounding off the top 25 we have Cougar Town star Courteney, who's approaching 50 and can still give girls half her age a run for their money.

Looks like age really is just a number after all!
