Riverdale's Madelaine Petsch Shows Eye-Popping Rear View In Black Bikini

Madelaine Petsch heats up social media with new bikini photos!

The "Riverdale" star took to her Instagram account and shared a series of tantalizing snaps that got her 23.3 million followers talking.

Petsch showcased her enviable curves in an all-black two-piece swimsuit for her day out in the sun. The set included a halter-style top with thin straps secured behind her neck -- accentuating her slender arms. It also had a plunging neckline that left an eyeful of her cleavage well on show.

Below, the actress rocked matching bikini bottoms featuring an insanely high-cut style that put her slender pins on display. The scooped front also allowed the redhead beauty to showcase her taut midsection.

The first photo showed Petsch lying directly on the boardwalk with her arms spread and one knee bent as she closed her eyes, feeling the heat of the sun on her skin. In the next slide, the 30-year-old was snapped reading a book while lying on her front and sporting a light snakeskin bikini.

As for the fourth image, Petsch flashed a big smile while out in the sun in her black swimwear. The last image of the American-South African star showed her standing on the boardwalk with her back to the camera -- flashing a jaw-dropping rear view.

Petsch captioned the share: "Reminiscing about lathering spf 50 on in the sun."

The new addition to Petsch's feed proved to be a popular one. After only a few hours, the upload received close to 500,000 likes and over a thousand comments. Countless fans dropped compliments and praise, mainly about the actress' flawless figure. Some of them opted to drop emojis to get their point across.

One person told Petsch, "You look absolutely stunning," while another commented, "Dream body with a dream face."

A third user added, "So beautiful as always!"

The fourth admirer deemed Petsch as "body goals."

Petsch made her relationship with Tyga Instagram official just last month. The internet debut happened two months after the "The Strangers" star sparked romance rumors with the 35-year-old rapper.

In a post posted on April 22, the actress dropped a series of snaps, including one that saw her getting cozy with the "Taste" hitmaker during the second weekend of Coachella. Petsch sported a white silk top with washed gray jeans when she rested her head on Tyga's shoulder as he looked at his phone.

In another picture, the duo was seen hugging while staring into the night sky.

Kylie Jenner's ex-boyfriend also published snaps from their date night on his own Instagram page. A picture showed the couple relaxing on the festival's grounds.

The post comes after Petsch and Tyga were spotted on several occasions in California earlier this year, particularly in Los Angeles. They were first spotted on Feb. 19, during a courtside date at the Los Angeles Lakers vs. Charlotte Hornets basketball game at Crypto.com Arena.
