This would be a very difficult question!
Ch-ch-check out the brand new teaser for upcoming I Am Cait episodes (below!):
Is it already time for those on again rumors to start up??
And you know the saying, former teen couples who birthday party together are probably doing something else more scandalous together. Wink wink!
Selenita supposedly held her big birthday party that we hear was gypsy-themed at Revolve Beach House in Malibu, which is where the Biebs popped up…
…although, clearly not in costume (above)!
The Biebs reportedly not only showed up after Selenita's parents left - how convenient - but he also supposedly left with the birthday girl herself!
That's right, even though he apparently came with buddy Jaden Smith, the Biebs might have bagged Selenita yet again!
