Emma Watson's Popular Pose: 'Peeking Her Butt' In Bikini

Emma Watson had Instagram in a frenzy as she showed off her stunning figure in a skimpy bikini bottoms look last year. In a photo promoting the Prada Beauty brand she is signed to, the 33-year-old actress sent out sunkissed vibes as she played around with a cute dog while on a boat, although Women's Health was more focused on the "peek of butt" the image showed. Channeling her signature elegance and effortless sense of elegance, the British sensation rocked a chunky knitted sweater paired with tiny swimwear briefs as she highlighted her toned legs, but with that cute doggie making her smile, fans couldn't help but melt.

Scroll for the photo. Looking blissfully happy amid bobbing ocean waters, Emma folded her legs as she sat on a boat, using both hands to hold her four-legged friend up opposite her face. Smiling at the pooch as she rocked a bandana, the Beauty & The Beast star drew the eye from her slender legs to her peachy rear, where a minuscule pair of white bikini bottoms with string ties highlighted her pert rear.

Throwing in fall accents via her cable knit sweater as she flashed her stomach in the sun, Emma added in pops of brown from her bandana, otherwise keeping things simple as she wore a lightweight layer of foundation and blush that brought out her delicate features. A dog emoji was the only caption as the Harry Potter favorite tagged Prada Beauty.

"What an amazing photo! You are so beautiful! My most favorite actor," one fan wrote. Over 2.5 million likes have been left, including celebrity ones. Actresses Reese Witherspoon and Penelope Cruz both sent love via a like. Emma may own Prada Beauty, but the fashion side of the brand is busy joining forces with other celebrities. Model Kendall Jenner is now signed to the label, with sister Kim Kardashian this year putting on a visible Prada display on Instagram as she donned an outfit bearing the brand's logo.

Also plugging Prada Beauty was the above photo as Emma rocked a studded, cut-out bathing suit in black while posing with a surfboard. The star actually mentioned surfing last April as she celebrated her birthday on Instagram.

"This is 33. Holy moly. Before 29 I hadn’t even heard of a Saturn Return as a concept. Let’s just say that now I am well acquainted," she wrote, adding that she "stepped away from my life - I learned to surf (badly),?‍♀️ I rode some horses (?that went better), I did a lot of therapy (YESS therapy!)."

Fans got yet another Prada mention as Emma shared this ab-flashing shot of herself in the sunshine. Rocking the Prada logo on her black skirt, the actress peeped some underboob as her cropped shirt rode up a little, but the feel was classy as ever as the A-Lister earned herself some cash.
