It's also the latest example of the social media-focused, nothing-is-secret, celebrities-are-fair-game world we live in.
The media storm began with a dimly lit, secretly taped video of Azalea's fiance, Lakers shooting guard Nick Young, talking about meeting a younger woman in a nightclub.
The video, according to the Los Angeles Times, was taken without Young's knowledge by Lakers teammate and 20-year-old star point guard D'Angelo Russell.
"You was 30 and she was 19?" the voice, reportedly Russell's, asks Young.
The video was then posted on celebrity gossip site Fameolous.
Russell has been shunned by "ticked off" Laker teammates for breaking an unwritten locker room bro code, ESPN reporting that Russell sat by himself at a recent team breakfast meeting.
Azalea appreciated seeing the video and, via Twitter, thanked Russell for taking it.
"hmmm i see D Angelo Russell is trending ... I actually liked his film. Thanks bro," Sydney-born, Mullumbimby-raised rapper Azalea wrote on Twitter just after midnight on Wednesday (local time).
The story, with its celebrity-sport crossover, has exploded in the US.
It has taken air time away from presidential candidate Donald Trump's shenanigans, with "Lakergate" debate raging across regular TV news programs, ESPN and other sports networks, talkback radio and TMZ and other gossip sites.
There are calls for Russell, scheduled to earn more than $US30 million ($A39.26 million) in his first five years in the NBA and who was supposed to be one of the saviours of the once great Laker franchise, to be traded to another team.
The Lakers have had an historically dismal 15 win, 59 loss season, including a 48-point defeat to the average Utah Jazz earlier in the week when the scandal first rumbled.
Laker fans have been cheering each loss because the lower they finish on the NBA standings the better chance they have of getting the number one pick in June's NBA Draft.
The expected number one pick is Melbourne-born 19-year-old Ben Simmons, a friend and former US high school team-mate of Russell's.
Simmons and Russell were supposed to create a dynamic duo for the Lakers.
But, today, Azalea's wedding plans with Young appear shaky.
Simmons, a longtime Laker fan, might not be so keen to begin his professional basketball career at what is a crumbling, toxic Lakers franchise.
