Her social media reach is massive, with 23.5 million followers on Twitter, a Facebook page "liked" more than 35 million times, an astounding billion music video views on VEVO and more than 200 million YouTube views for her cover of "Let It Go," the Academy Award-winning song from "Frozen." In addition to her musical accomplishments, Lovato has become a fixture on television, having had a recurring role on the fifth season on FOX's GLEE, as well as her role as judge and mentor on Seasons Two and Three of FOX's "The X Factor." The multi-talented star also wrote the inspirational book "Staying Strong: 365 Days A Year," which debuted at No. 1 on the New York Times Best Sellers list. She is releasing a follow-up journal this fall. Lovato recently signed on with Skechers for a global footwear marketing campaign which will be featured across multiple platforms, including television, print, online, outdoor and point of purchase.

2014 is primed to be the year of Rita Ora. She was unstoppable and dominated the U.K. charts with the release of her No. 1 certified Platinum debut album, "Ora." The Roc Nation/Columbia artist is now readying to release her newest full-length album, propelled by the hit single, "I Will Never Let You Down." Ora had a phenomenal rise in 2012, which continued in 2013. She was the only artist to have three No. 1 singles in a row and proved herself as a force to be reckoned with on the stage, including her European tour with rock giants Coldplay, supporting Drake and playing every major U.K. music festival, as well as her headlining "Radioactive" tour across the U.K.
