Brian was at the airport in L.A. this week when we asked if Lindsay ever comes up in his prayers -- and Brian replied, "Unfortunately, no."
Deeply religious Backstreet Boys singer Brian Littrell is far from the perfect Christian -- telling TMZ, he doesn't pray for everyone like he's supposed to ... and he definitely doesn't pray for Lindsay Lohan.
He adds, "I'm probably breaking a lot of ministers' hearts. It's like, 'He's a Christian. He should pray for everybody' ... But she's not in my prayers at night. I'm sorry."
This might explain a lot.
