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 -- working on Les Misérables. And don't forget, Justin and Nick are now also friends after they bonded of Nick's nickname for Justin, "Bustin Jieber."
