We have a double dose of Demi Lovato music news for you Lovatics out there today. First up, there are rumblings out there as to which track off 'Demi' will be the fourth single off the album. Secondly, an unreleased Spanish language song titled 'Besame Mucho' has hit the Internet. 

Popdust (via Josepvinaixa) reports that the track 'Really Don't Care' will be the fourth single to hit pop radio in the U.S. after 'Heart Attack,' 'Made in the U.S.A.' and 'Neon Lights.' 'Really Don't Care' pairs Demi with British star Cher Lloyd and has an upbeat bubblegum dance sound, which would make it a great potential summer hit. Even though it hasn't been released as a single officially, the track has already hit the Billboard Hot 100 in both the U.S. and Canada.

Meanwhile, an unreleased Demi track titled 'Besame Mucho' has hit the Internet. The Spanish-language song was originally intended for her third album 'Unbroken' but was ultimately scrapped. The song has found its way online, however, and you can hear it below.

Lovatics, do you think 'Really Don't Care' will be a summer hit? And what do you think of 'Besame Mucho'?
