Here's one way to get over TAYLOR SWIFT:  Celebrate your 19th birthday with a STRIPPER.  That's what HARRY STYLES of ONE DIRECTION did on Friday night.

--It all went down at a bar in England.  NIALL HORAN and some other friends were with Harry, and the stripper was dressed as a cop.  Unfortunately, they weren't in a strip club, so she couldn't get naked.  But she did give him a lap dance.

--Harry says, quote, "It was great.  I was in stitches . . . it was really funny."  (--Check out some pics here.)
