Justin Timberlake was on a British talk show - and did 5 shots of tequila in 10 minutes!!

Early Wednesday morning, a big hailstorm did some damage in a small town outside of Houston.  And the local news talked to a woman named Michelle Clark, who gave an AWESOME interview about what happened.  It's almost like she took lessons on how to do interviews from Sweet Brown. 

Not surprisingly, JUSTIN TIMBERLAKE capped off his week on "Late Night with Jimmy Fallon" by teaming up with Jimmy to do another "History of Rap" song.  This is their FOURTH one.  This time they did a sampling of everyone from Jay-Z and The Notorious B.I.G. to Eminem and 2 Live Crew.

--Meanwhile, QUESTLOVE . . . from Jimmy's house band, THE ROOTS . . . says there's a "part two" to Justin's new album, "The 20/20 Experience".  (--Which comes out tomorrow.) 

--He posted this on a message board:  Quote, "Spoiler Alert:  '20/20' Volume Two comes out in November.  10 songs now . . . 10 songs later . . . 20 vision."  There's no official word on this potential sequel.
