Because she is in Europe shooting Monte Carlo, good friends Selena Gomez and Justin Bieber haven't seen each other in a long time. But that's not stopping Justin from tweeting Selena some brotherly advice.
The "Somebody to Love" singer wrote, "@selenagomez hope all is going well in Budapest. Watch out for crazy Nick for me. Dude is a wild man...haha"
Who is Nick? Nick Jonas, Selena's ex! Nick is also in Europe -- London to be more specific --Â working on Les MisÃ©rables. And don't forget, Justin and Nick are now also friends after they bonded of Nick's nickname for Justin, "Bustin Jieber."
Why do you think Justin is warning Selena about Nick? Do you think Nick and Selena are going to reunite while they're both in Europe?
