After spending Christmas with Chris Brown, Rihanna made sure to post a picture of them engaging in one of their favorite activities — smoking.

"Thug life #merrychristmas,” read the caption on a black and white photo Rihanna posted online  that depicts her sitting on the hood of a car smoking, while Brown stood in the foreground, also smoking either a cigarette or possibly marijuana.

Brown and Rihanna spent the holidays together, taking in a Lakers game courtside in Los Angeles.

Earlier this week, Rihanna reportedly cursed out a fan who commented on her love of smoking weed. The singer posted a picture of herself smoking marijuana to her Instagram account with the caption, "Friday night gettin a lil fuzzy." In response, one follower wrote, “She’s going to end [up] like Whitney if she keeps doing drugs like she’s doing now.”

Whitney Houston passed away in February after being plagued by drug use for years.

By 2000, Houston had been married for eight years to singer Bobby Brown. Their marriage was widely known for fighting, scandals, drug and alcohol-related arrests. Houston's career was dogged by heavy drug use, for which her family blamed Brown.

In a 2009 interview with Oprah Winfrey, Whitney said her mother, gospel singer Cissy Houston, arrived on her doorstep with sheriff's officers and a court order for drug intervention. 

Rihanna apparently did not appreciate the comparison, replying to the Instagram follower, “Yea cuz Whitney overdosed on a joint. [Expletive] outta here you weak [expletive]!!”
