Ke$ha's Tiger Mask Cover-Up

Getting costumed up, Ke$ha was spotted sporting a tiger mask as she left her hotel in New York City on Tuesday (August 17).

Accompanied by a bodyguard, the "TiK ToK' singer playfully strolled past paparazzi as she hopped into a cab to run errands during a day off from stage duties.

In related news, Ke$ha is drawing to the end of her opening act efforts on Rihanna's "Last Girl On Earth" tour.

As for her following plans, she told MTV, "I'm finishing up this tour and going in to start writing again — some more music for you guys — and will continue touring throughout the rest of the year. I don't know who's going to go on tour with me yet, but I think I'll be going on my tour later this year perhaps."

Ke$ha adds, "I will definitely be playing some shows and, really, I'm just working on developing my live show. It's all I think about. I have dreams and then nightmares about my live show. I want to make it so good, like the best show ever."
