The Brit Awards went down earlier this week.  They're England's version of the Grammys.  JUSTIN BIEBER was in town for the show.  And when it was over, he hit up an after-party where JUSTIN TIMBERLAKE was performing.

--But he didn't go alone.  He took a British singer named ELLA-PAIGE with him.  There's no word if they went as friends . . . or more.  But apparently, she's good friends with a stylist who's touring with Justin.

--Meanwhile, "Life & Style Weekly" says that SELENA GOMEZ has her sights set on HUNTER HAYES . . . a country singer who once opened for Selena's good friend TAYLOR SWIFT.

--A source says, quote, "[They] flirted and traded phone numbers!"
