Demi Lovato, wearing a one piece suit with a long sleeved shirt covering her bottom matched with very high heels, had a not-so-cool fall during the pool party she organized to launch her newest single "Cool for the Summer."  A crowded pool witnessed Lovato's 'great fall' last Sunday afternoon in WateMarke Tower in Los Angeles.

According to E! Online, Twenty-two year old Demi Lovato launched her new single 'Cool for the Summer' last Sunday at the WaterMarke Tower, Los Angeles, Califronia. Unfortunately, Lovato slipped and made a hard fall. But it was so professional of her, because after slipping she immediately rose up and jumped in the pool along with fans.

Though it seemed like Demi Lovato was hurt so badly, she looks like she was not hurt at all. After the uneventful scene, she then traveled to San Francisco, to perform another concert in Temple Night Club. Demi's latest single hit the charts and climber up immediately.

Demi Lovato indeed is very famous, as when she posted on her social media account her new cover-up tattoo, an Ashley McMullen claimed that she was the one who inked the purse lips tattoo on Demi's wrist.

On MTV.com, McMullen even put some hashtags like "#demilovato #scumbag #turd #claimstobesober #drankallthebeer #peepeetoiletseat #yousuck."

Demi Lovato did not let this pass, posting her reply in Twitlonger where she also deleted it after awhile. On Demi's post, she wrote "I can't blame you for getting the tattoo, I take full responsibility for that but if the issue here is you wanting credit, maybe next time you should wait for the person to get your tattoo sober so they would actually remember getting the tattoo in the first place."

Meanwhile, Demi's new video will make you realize that she is not just an ordinary singer, but she has definitely has a signature voice! Some fans though say that her video "Cool for the Summer" has some similarities to Katy Perry's 'I Kissed A Girl.'
