Spontaneous combustion, anyone?

“Spontaneous Combustion was a personal favorite,” Jeffre said in a newUs Weeklycover story.

Keep in mind that this brainstorming session didn’t involve any producers or a label.

Unlike many star-status boy bands, 98 degrees formed independently before snagging a record deal.

Timmons said they originally started out with the name Just Us before later considering calling themselves First Four.

Ultimately and thankfully they landed on 98 degrees, and there was no turning back.

“We voted on it,” Drew Lachey said.

“We wanted something that represented the mood and tone.”

“Our manager, believe it or not, had a really hot girlfriend.

She was like, ‘Why not call yourselves 98 degrees?’

And we were like, ‘Bingo!'”
