Bieber recently split from his longtime lover Selena Gomez over speculation he was flirting with model Barbara Palvin at the Victoria's Secret Fashion Show last autumn (12), while the One Thing hitmaker was recently accused of cheating on his girlfriend Perrie Edwards with a waitress.
Malik jetted back to Britain from France over the weekend (27Jan13) in an effort to smooth things over with his longtime love, while Bieber opened up about his broken heart in a new Billboard.com interview - and now the Baby hit maker and One Direction's Malik are hoping to let loose and get away from it all during a Sin City vacation.
The Baby singer tells Yahoo!, "I am there for him whatever he is going through - that is what buddies do. If he wants to go away and have a little trip to get away from things that is cool. We could go and do a weekend in Vegas and just get away from everything. We are blessed to be doing what we are doing - but I know how tough it can be dealing with something that should be private in the public eye. All you want is privacy but you know it isn't going to happen.
"All the One Direction guys are my buddies - but I do get along really great with Zayn. We hang out a lot and we have a whole bunch of common interests and find similar stuff funny. He is a really good guy."
