Cuban born singer/songwriter Camila Cabello (Epic Records / SYCO) is no stranger to the spotlight. Beginning her official solo career after four years in Fifth Harmony, Cabello released her much-anticipated debut single, "Crying in the Club," to rave reviews. Cabello's newest song "Havana," was released in August and is currently exploding on the charts. It reached No. 1 on the pop radio chart, which makes this her second top 40 No. 1 as a solo artist.  The track was No. 1 on the iTunes overall top songs chart, No. 2 on the Spotify Global chart and hit No. 1 in 80 countries around the world. The song has over 400 million streams and 304 million YouTube views.  She had already earned a chart-topping smash with the recent double platinum-certified hit "Bad Things" with MGK. The track generated over 240 million Spotify streams. As a result of its success, she became "the first female artist to hit No. 1 on Top 40 Radio with and without a group." Cabello was recently featured on J Balvin and Pitbull's "Hey Ma" from the worldwide hit film "Fate of the Furious" and its chart-topping soundtrack as well as "Know No Better." She has also collaborated with Shawn Mendes for the platinum-certified duet, "I Know What You Did Last Summer," which reached 10 at pop radio and hit No. 20 on The Hot 100 chart. Her debut album is due out January 2018.

Multiplatinum and Grammy-nominated recording artist, actor and award-winning songwriter, Nick Jonas, released his self-titled debut album in November 2014. The critically acclaimed album included the double platinum and No. 1 U.S. radio hit, "Jealous," and his sultry chart-climbing radio single, "Chains." A recipient of the Songwriters Hall of Fame's prestigious Hal David Starlight Award, Jonas released his sophomore solo album, "Last Year Was Complicated," in June 2016. The album, which included the platinum hit "Close" featuring Tove Lo, debuted as the No. 1 selling album of the week. In 2017, Nick released a new single "Find You" off of his upcoming album. Jonas also wrote an original song titled "Home" for the movie "Ferdinand," released by FOX Animation. As an actor, Jonas garnered unanimous critical praise for his lead role in the 2016 Sundance Film Festival favorite "Goat," which was produced by and featured James Franco. He also appeared in a guest-starring role in Fox's horror-comedy series, "Scream Queens." Jonas starred in the gritty television show "Kingdom," a mixed martial arts drama that premiered in the fall of 2014. Next, Jonas will appear alongside Dwayne Johnson, Kevin Hart, and Jack Black in Sony's reimagining of "Jumanji," out December 20. Jonas is currently in production on Lionsgate's post-apocalyptic thriller, "Chaos Walking," which also stars Daisy Ridley and Tom Holland, and is scheduled for release in March 2019.
