'World's Sexiest Nurse' Lauren Drain Has Some 'Fun' In A Red, White & Blue Bikini In Throwback Post

Blond bombshell Lauren Drain delighted her Instagram followers yet again recently, posting a throwback clip wherein she sizzled in a sporty red, white, and blue bikini. Though the exercise fanatic is known for her work ethic at the gym, she also knows when to let her hair down, calling the clips "fun content" in her caption.

The stunner first found fame after documenting her fitness journey. As a cardiac nurse, she realized that few people she treated were athletes, and accordingly, decided to take her own health seriously. It is a decision that has led her to develop her own personal training business -- gaining nearly 4 million followers on Instagram along the way.

In addition to her primary account, Lauren has a second one dedicated more to her personal training business, which is where she posted this recent update. For the occasion, she wore a red scoop-neck bikini top accented with white piping. The bikini bottoms feature a thong cut that leaves little of her derriere to the imagination. The bottoms appear in a contrasting blue color and also feature white piping.

Lauren's most recent video share opens with a view of the model from behind. She raises her arms and flashes the peace sign while in front of a beautiful vista, one comprised of a bubbling stream, pine trees, and mountains. The pose shows off Lauren's perky posterior, toned from her time at the gym.

Lauren accessorized with some mirrored sunglasses, which are visible as she smiles at the camera over her shoulder.

Next came a clip of Lauren perched on a fallen tree trunk, a picturesque waterfall behind her. Though her hair was loose before, it was styled into pigtailed braids this time around. She also displayed a pair of trendy white sneakers.

Though this clip is very short, Lauren gives viewers a cheeky grin before the next part of the video begins.

The last segment of footage consists of Lauren once again sitting on a tree trunk. Her back is to the camera as she flashes the peace sign once more. The finale is also shot from much farther back, giving a broader sense of the surrounding wilderness.

The upload earned over 3,700 likes and around 25 comments.

"Brave and beautiful," one fan gushed, adding three red hearts to their remarks.

"Gorgeous," seconded another user, two apple emoji making an appearance alongside their comment.

"So very beautiful," added a third follower.

This is not the first cheeky throwback that Lauren has shared this week -- she also uploaded a throwback yesterday wherein she wore a revealing bodysuit, as was covered by The Inquisitr.
