Jen Selter, one of today's famous social media celebrities, has recently celebrated her 21st birthday at the Tao nightclub in Las Vegas. Selter is a fitness enthusiast who shares her fitness tips and workout routines on Instagram. Selter is known for her ridiculously-good body, and fills her account with workout pictures, selfies, and of course, the thing that made her famous--her perfectly-sculpted derriere. Her signature move is called "Seltering," where she poses on her hands and feet while her famous bottom protrudes.

The Las Vegas Informer reported that during the August 9 party, Selter first had dinner with friends at the famous Tao Asian Bistro before partying. They group then headed upstairs to the Tao Night Club, where they were given VIP treatment. Selter was reportedly surprised with a three-tier birthday cake and an appearance by the famous Tao Mirror Man.

Another Instagram celebrity was also at the venue. Poker player Dan Bilzerian, who has been dubbed as the "Instagram Playboy" because of his photos with scantily-clad women, also joined Selter in her birthday bash that night. Bilzerian even shared a photo of him with Selter, with the latter placing a delicate arm around his neck as they gaze to the camera. It was not made clear if he was in the club for a different event, but the poker player posted a photo of him and Selter, with a caption that read, "Happy 21st birthday @jenselter and her #neverendingass." 

An insider told New York Times' Page Six, who claimed that there was some flirting action going on: "They chatted and flirted a little, and took photos together."

After Selter posted on Instagram what looks like an invitation to her big day, she posted a sexy photo of herself wearing a bikini bottom that looked rather revealing. She then followed this up with a photo where she holds balloons with a caption that read, "21 balloons for the most unforgettable 21st birthday in Sin City!! Thank you so much for all of the birthday love. #Time2Party #BdayWeekend."

Seems that she had a rather lovely weekend indeed.
