JESSICA ALBA AND JESSICA BIEL STAND UP FOR REVLON

Both, Jessica Alba and Jessica Biel strapped on their sneakers for a good cause in New York City on Saturday.

The two Hollywood hotties were among the many participants running the streets of the Big Apple during the 14th Annual Entertainment Industry Foundation Revlon Run/Walk for Women.

Tweeting about the exercise outing, Miss Alba happily wrote, “The energy here @revlon run/walk is amazing 20,000 people are here 2 participate. This is 14th year & we’ve raised over 60millions for womens cancer!”

Alba, who is expecting her second child and fresh off of celebrating her 30th birthday a few days prior, added, “Hanging @revlon run/walk w @jimmyfallon Jessica Biel n @DrOz."

For those interested in giving to the charitable endeavor, the Revlon Run/Walk supports organizations and programs that research the cause and cure of women's cancers and provide support programs for women's cancer patients and their families.

Proceeds from the Run/Walk are distributed to a variety of charitable organizations leading the fight against women's cancers.

JESSICA BIEL - THE HAWAIIAN BIKINI BEACH BABE

Regularly perched atop of the many hottest body lists, Jessica Biel showed that she's still got it during a beach outing in the islands of Hawaii.

The "Powder Blue" beauty donned a skimpy animal print bikini top paired with white bottoms as she soaked up some rays before going snorkeling and playing with a friend's baby in the water.

Having since finished up her relaxing getaway, Jess is now back home in Los Angeles - as she was spotted out this morning taking a hike with a gal pal and their pooch pals.

Aside from her week's doings, Miss Biel is once again facing cheating rumors tagged to her longtime beau Justin Timberlake.

According to Life & Style, the "Sexy Back" stud sent text messages claiming to Olivia Munn which stated that his relationship with Biel is over.

Their source alleged, "She had several new text messages from Justin on it. They'd all been sent very recently, the last few weeks of December."

The Life & Style insider added, "She's super flattered but she's not stupid. She's not expecting it to go anywhere – but she'd love it if it did!
