Two-year-old Landon and 10-month-old Logan were taken away from Major's apartment in Boca Raton by officials at Florida's Department Of Children And Families after they obtained a video featuring an altercation between their parents, reported TMZ.
Michael's mother flew in from Long Island and the kids were released to her guardianship at her son's home.
"Michael and Kate can both see the kids, but only if their grandma is present," a source said.
