The episode is scheduled to air March 5.
"Gangster's Paradise" singer Coolio lives with his girlfriend, Mimi, and her three children -- Majaniek, 14, Javante, 10 and Tariq, 5 -- in a suburban community in Las Vegas.
"When he's not touring or hanging out with friends, Coolio spends the majority of his time sleeping or relaxing at home, while Mimi works as a bartender and an exotic dancer, in addition to taking care of their home and raising her three children," ABC said in a synopsis said.
McGrath, who is perhaps best known as the front man of the band Sugar Ray, and his wife, Carin, are the parents of 2-year-old twins, Lydon and Hartley.
"When self-sufficient Mimi arrives in Los Angeles, Calif., to swap lives with Carin, she is surprised to see a maid, a nanny and Carin's parents -- who live with them full time. Mimi is flabbergasted when she sees how the twins have complete control over the household," the synopsis said. "She also zeroes in on Mark's 'helicopter parenting' and thinks that his hovering over everyone's interaction with the twins is a problem.
"It's a far cry from the standoffish behavior Coolio displays when Carin arrives: Sleeping the day away and hanging out with his friends, he spends little time at home with the kids or helping with the household duties."
