For the most part, it's been the typical A-list star promoting new project stuff, and Cameron has maintained her usual balance of outspoken, yet polite.
Earlier today, however, when an Australian radio DJ made an insensitive remark about Diaz' friend and former co-star Drew Barrymore, Cameron was having none of it.
Cameron called into an Aussie morning show along with Sex Tape co-star Jason Segel, and things quickly went south as host Kyle Sandilands decided that Barrymore's near-deadly childhood drug addiction was ripe comedy material:
The conversation started innocently enough with Sandilands remarking that the actress who plays Cameron's daughter in Sex Tape reminds him Drew Barrymore.
Cameron agreed, and Sandilands quickly offered up this gem:
"Let's hope she misses out on the Drew Barrymore drug years, because those were a great thing to watch, but not so good to be in I'd imagine."
Diaz went silent for a moment, before responding, "I'm sure, Kyle, you've never been through a drug phase, have you? Or alcoholism or anything like that? Pretty clean? Always did it right? Congratulations!"
Following a second or two of stunned silence on Sandilands' side Cameron blurted, "We have to go now," and quickly hung up.
Take note, obnoxious radio hosts: don't trash talk Diaz' friends or she'll go full Killer Cam on you.
