Jen Selter, the fitness model who became a star on Instagram because of all the work she's put into developing her personal brand—which, in this case, is a euphemism for "butt"— celebrated her 21st birthday in Vegas over the weekend. Also there was Dan Bilzerian, another Instagram star known mainly for his millions of dollars and the time he threw a porn star off the roof of his mansion and missed the pool.

Was this Insta-singularity more than a coincidence? It's not unusual for Bilzerian, a high-stakes poker player, to spend time in Vegas, but Page Six reports they were seated near each other at the Marquee Las Vegas/ Bilzerian "wanted to meet her," the tabloid reports, so she went over to his table.

"They chatted and flirted a little, and took photos together," "a spy" told Page Six.

But is she dating him? Probably not. Bilzerian told Howard Stern in July that he had just broken up with someone because having a girlfriend didn't suit his playboy lifestyle (this is not hard to believe from a guy who uses the hashtag #dailypussy.) He is an avowed fan of Selter's #neverendingass, though.

Also, in case you were wondering, the other woman in the photo is Chelsey Novak, who has 82,000 Instagram followers of her own. "These two people thoooo [clapping emoji] [OK sign emoji] [monkey covering its eyes]," she wrote when she posted it to Instagram.

I don't speak fluent emoji, but make of that what you will.
