Bam Margera is tapping into his own past while weighing in on Britney Spears’ situation ... telling TMZ he’s more than willing to help the pop star if she ever needs a hand.
We caught up with Bam Monday in L.A., where he told us ... back when he was getting treatment at Lamar Odom's rehab clinics, Britney actually lived down the street, and he considered knocking on her door to offer assistance.
DAD CRIED THE WHOLE WAY HOME!!!
Watch the clip, because Bam makes it clear it’s not really him who could help Britney, but his wife, Dannii Marie -- a stretch coach/nutritionist who laid down the law with him, saying if he drank alcohol, it was basically the same as cheating
Bam also tells us he gets fans' concerns after recent pics of Brit out at a restaurant.
