Pop star Chris Brown posted pics of himself smoking out with his friends during stop through Amsterdam.  See the flicks inside and get deets on the River Island campaign Rihanna directed.

As his "Carpe Diem" tour treks through Europe, Chris Brown tooka break from dancing and smoked out with a few friends in Amsterdam.

Chris posted pics on Instagram of himself at a "coffee shop" in Amsterdam.

He and his crew seemed to enjoy the variety of "legal" herbs offered.

While smoking, Chris showed off his kicks.....

And the rest of the crew showed off their expensive bling.

Also......

Chris' mother, Joyce Hawkins, was greeting by fans outside of the Conrad Hotel in Dublin, Ireland.  The fan were waiting for Chris to return following his show yesterday.  The next stop for Chris is Antwerp, Belgium.

And.....

Chris' "friend" Rihanna spent yesterday directing and starring in her spring/summer campaign for retailer River Island (whose line she helped design).  The shoot, held in LA,  starred Jourdan Dunn along with Rihanna herself.  

She tweeted,

“My bitches so Bvalgari… Just directed my first ad campaign for my new collection with River Island, Spring/Summer 2013!! And that’s a wrap at the end of a 2 day shoot w/ MARIO SORRENTI."

Though the "friends" aren't together now (due to work commitments) a source close to Rihanna says the singer compares their friendship to that of Whitney Houston and Bobby Brown.  The source told Hollywood Life, 

“She loves that old Whitney jam and knows that she and Chris have so much in common that just bonds them. They get each other just like Bobby and Whitney. You could see it’s like real love with she and Chris – like ain’t no bullshi**ng. The s**t is magical and it’s real.”

Isn't that a little disturbing?
