SOCIAL media star Karin Hart has outdone herself after revealing major underboob in her latest Instagram post.

The Paige Spiranac rival, 34, posed in front of a scenic view of the waters of Clearwater, Florida.

Hart regularly shares golf content and lifestyle photos with her fans.

She also has built an impressive online following with over 174,000 Instagram followers.

On Saturday, Karin took a break from her usual travels to the golf course.

Karin took to Instagram and was seen in a small patterned Dior bikini.

She showed off her underboob in the process while also revealing plenty of legs in a tiny swimsuit.

Hart was seen standing near the Florida waters as fans flooded the comments with praise.

One stated: “Looking as gorgeous as always.”

Another added: “God bless you Karin.”

And a third said: “You look great in that bikini Karin.”

Hart has become a rival to Spiranac for the social media crown due to her combination of golfing skills, beauty, and online fame.

Karin grew up in southern California before relocating and moving to Colorado when she was young.

She currently resides in St. Petersburg, Florida.

The 34-year-old Hart also leads her own company, iHart Marketing.
