Superstars Bruno Mars, Pitbull, Justin Timberlake and Pharrell Williams are all facing off for the title of Favorite Male Singer at the 2014 Kids' Choice Awards. All four performers have had incredible success over the past year. Which artist is most deserving of the KCA? 

Bruno Mars is super hot right now, and his popularity has only increased since his flawless half-time performance at the 2014 Super Bowl. This year, he has already won a Grammy Award for Best Pop Vocal album and had incredible success last year as well, with several of his songs ('Treasure,' 'Gorilla'  and 'Young Girls,' to name a few) scoring enviable spots on the charts.

Pitbull has had quite the busy year, working with everyone from Kesha to Jennifer Lopez to Austin Mahone. The Miami rapper has been featured on numerous songs over the past year, but his most popular is his own hit, 'Timber,' featuring Kesha. (The song landed the No. 1 spot on charts worldwide.) 2014 is only looking up for Pitbull, as he plans to release his upcoming eighth album at some point as well.

2013 was a phenomenal year for Justin Timberlake, who released 'The 20/20 Experience,' his first album in seven years. The album, which spawned the hit singles 'Suit & Tie' and 'Mirrors,' was an incredible success for the veteran performer, becoming the best-selling album of 2013 in the U.S. and nabbing JT an American Music Award for Favorite Soul/R&B Album. JT's year just kept improving musically, embarking on a summer stadium tour with Jay Z and later on his own 20/20 Experience Tour.

Pharrell Williams (and his infamous ten-gallon hat) has been everywhere as of late, riding the success of his 'Get Lucky' collab with Daft Punk as well as his own tune, 'Happy,' which was even nominated for an Academy Award. 2014 also marks the release of his latest album, 'G I R L,' which debuted at the No. 2 spot on the Billboard charts and has been selling like hotcakes. The album has even become the fastest-selling of 2014 in the United Kingdom. Wow!

You can vote for Bruno Mars, Pitbull, Justin Timberlake or Pharrell once an hour until the poll closes at 7:59 PM on Saturday, March 29.
