Katy Perry and Jessica Alba turn up the heat with skin-baring looks: PHOTOS

The former "American Idol" judge wore her hair in a short bob with the front pieces styled in a wet look. She wore a sequined headpiece, matching the material of the dress, which covered her hair and neck.

She kept the rest of her accessories to a minimum, allowing the futuristic dress to do all the talking.

The photos show Alba lounging on the sand in sunglasses, a sunhat and a red and white patterned bikini. Other photos show her covered in sand and reaching out to hold her son's hand as they get closer to the water, later turning around and posing with each other for the camera.

"So cute love your outfits," one follower wrote in the comments section. Another added, "Mommy's got it going on," while a third added "Only actress that never aged."

Millie Bobby Brown took to Instagram to share a series of photos featuring her dyeing hair back to its signature brown, spending time with family and of herself posing in front of the beach.

In the photo, the "Stranger Things" star can be seen standing in front of the ocean in a red bikini with gold detailing as she posed with her arms in the air while holding a blue and white scarf.

"Couldn't help myself," she captioned the post.

Fans of the actress were quick to flood the comments section with compliments, with one user writing "your photo dumps make my day, you make me so happy mills," and another adding, "the most perfect woman in the world."

She paired the look with dangling silver earrings and metallic gold heels and opted for a subtle smokey eye makeup look. The actress wore her blonde hair down, but swept up and off her face in a deep side part.

"Find someone who looks at you the way that I look at Danny and a burger," she captioned the post. 

"Life lately," Eva Longoria captioned a carousel of photos posted on her Instagram account, featuring photos of her spending time with her son and on set, the books she is reading, partying with her friends and lounging in her bikini.

The first picture posted in the photo dump features the actress sitting on a lounge chair in a cheetah-print bikini with her baseball cap, with the words "Tequilla Casa del Sol" written on it, covering her face.

"Like are you kidding me!? So gorgeous! The most beautiful woman on earth," one fan wrote in the comments section. Another added, "You look amazing. Lot of hard work, it shows," while a third wrote, "Beyond beautiful."

Mandy Moore walked the red carpet at the Fashion Trust U.S. Awards in a sheer long-sleeve top and matching skirt, both of which featured sparkly silver embellishments throughout. 

The "This Is Us" star's light-colored underwear was visible underneath the two-piece set, which she also paired with strappy nude high-heel shoes and a nude clutch purse. She kept her makeup natural and wore her hair in a middle part.

"Outrageously chic! LOVE this look so much," one fan wrote, while another added, "This outfit is everything."

The "Twilight" star kept her accessories to a minimum, opting for just one ring, black high-heeled boots. She also kept her makeup looking casual with a slight smokey eye, and wore her blonde hair in a center part.

Nina Dobrev gave her fans a cheeky look at her vacation in a recent Instagram post, sharing a photo of her standing in front of a window and looking out onto the ocean view, while wearing a red bikini.

She kept the caption playful, keeping it to just an emoji of a peach.

"Nina posting is my favorite part of the day!!!" one fan wrote in the comments section. Another added, "The view + Nina = perfection," while a third chimed in with, "Oh she served."

The Academy Award-winning actress paired the look with dangling diamond earrings, a silver Gucci clutch purse and metallic platform high-heel shoes. She kept her makeup looking soft, with a pink lip, a bit of blush and bold lashes, and she wore her signature orange hair in loose curls and a deep side part.

She posted a video of herself walking the red carpet on Instagram, captioning the post, "Went to the Oscars of Science this weekend."

"Always a Goddess," one fan wrote in the comments section, while a second user added, "you looked STUNNING!" A third fan also wrote, "always the best dressed."
