Ke$ha was spotted holding hands with someone (not sure if it’s a boyfriend??) at a Pool Party at Moorea Beach Club at Mandalay Bay, Las Vegas over the weekend.

Ke$ha who sings “TiK Tok” opened for Rihanna’s “Last Girl on Earth” tour at the same venue. On Tuesday, Ke$ha will be headlining the House Of Blues in San Diego and on Wednesday, Ke$ha and Rihanna will hit up the Staples Center in Los Angeles.

Ke$ha’s friends are wearing very interesting hats. I’m sure that had to draw some attention to the three of them – it was super h-o-t in Vegas yesterday – I can’t imagine how hot it felt wearing the hat.

It looks like Ke$ha painted her arms. Is this a new fashion statement??
