Backstreet's back, alright! They are about to get N'Sync with O-Town, and the temperature will most definitely be 98 Degrees and rising!

To the delight of boy band lovers everywhere, former members of the hottest guy groups of the '90s dropped a collaboration on March 28. That's right, the heavenly voices of Backstreet Boys' A.J. McLean, Nick Carter and Howie Dorough are now recorded singing with N'Sync's Joey Fatone and Chris Kirkpatrick, 98 Degrees' Jeff Timmons and O-Town's Erik-Michael Estrada.

The song, called "In the End," is a pop power ballad that features the classic harmonies we knew and loved from the pop music of that era. Lyrics give instant flashbacks to the late '90s and early '00s when the groups were topping the charts, including lines like, "In the end, don't want to see you fall apart/Don't want to hear your broken heart/Don't look back, nothing's gonna save us in the end."

Aside from giving fans what they'd always dreamed of, the nostalgic pop song also serves a purpose. The tune will be the theme song for the upcoming apocalyptic television movie "Dead 7," hence the occasionally dark lyrics and spooky whistling sounds in the background. The same former pop princes that lend their voices to the ballad will also be featured in the SyFy flick, which is a "Walking Dead" inspired futuristic zombie Western film co-written by Nick Carter himself. Nick stars in the film as Jack, while Joey Fatone takes on the role of Whiskey Joe, A.J. McLean portrays Johnny Vermillion, Howie Dorough stars as The Vaquero, Chris Kirkpatrick plays Mayor Shelby, Jeff Timmons takes on Billy and Erik-Michael Estrada plays Komodo.

The TV movie comes from the makers of "Sharknado," and also co-stars Nick's wife Lauren Kitt-Carter as Sirene, MADtv's Debra Wilson as the terrifying Apocolypta, and Olivia Newton-John's daughter Chloe Lattanzi as Trixie.

Of the project, Nick Carter told Buzzfeed back in July 2015, "Boy-banders, people from the late '90s, people who you love, fighting zombies in a post-apocalyptic world. Pretty crazy, right?" Pretty crazy, indeed!

The film premieres on SyFy on April 1.
