Monday was family day for friendly exes Mariah Carey and Nick Cannon.
The former couple proved once again to be masters of co-parenting 6-year-old twins Moroccan and Monroe, using the holiday as an opportunity to teach their kids about Dr. Martin Luther King Jr. during a trip to a museum.
“Celebrating today in honor of the Reverend Dr. Martin Luther King Junior at the Kidspace Children’s Museum,” the 47-year-old singer captioned an Instagram post, adding the hashtags “#Dream” and “#ThankYouDrKing.”

Carey and Cannon, who broke up in 2014 after six years of marriage, still spend plenty of time as a family, from fun-filled days at Disneyland to celebrating the twins’ birthdays to coloring eggs for Easter.
In May, their “friendly ex” status caused friends to even wonder if they’d rekindled their relationship.
“Mariah and Nick are getting along great,” the source told PEOPLE at the time. “Nick spends most of his time with Mariah and the kids. Mariah is great with Nick around. There seems to be hope that they will get back together permanently.”
