AceShowbiz - Cameron Diaz and Nicole Richie are not only friends, but also a pair of sisters-in-law. Nicole married Joel Madden in December 2010. Five years later, Cameron tied the knot with Joel's twin brother Benji Madden.
Back in 2020, the "Bad Teacher" actress reacted in a hilarious way to a fan, who reminded everyone of the pair's relationship. "Nicole Richie & Cameron Diaz are sister in laws and I feel like we don't talk about it enough," the fan tweeted. Cameron replied, "[twin emoji] ?!? [mind blown emoji] !!! [winky faces] @nicolerichie."
