Jason Filyaw admits that he's been "growing very close" with Brit Brit since their "special" relationship began. He also even used the L-word when describing his boner for her.

In an exclusive interview with TMZ, Jason describes himself as "very spiritual." And he wouldn't confirm or deny he's dating the pop star, but said, "I love her, I support her 100% and we are close."

As I reported yesterday, Jason's a 33-year-old rocker from the band Riva currently attending AA meetings with Ms. Spears.

Britney and Jason recorded music together in 2003. He says they've remained in touch, but met up in rehab where the lovin' is good.
