Matthew Morrison Reacts to Former Glee Costar Naya Rivera's Arrest: 'She's a Great Mom'

Matthew Morrison is championing his former Glee castmate Naya Rivera‘s parenting skills in the wake of her dramatic Nov. 25 arrest.

“She’s a great mom,” Morrison, 39, told PEOPLE exclusively at the Sherpapa X CampGOOP event on Sunday when asked about his reaction to Rivera’s misdemeanor domestic battery charge.

Two days after Thanksgiving, police confirmed to PEOPLE that the mother of one, 30, was arrested and charged with misdemeanor domestic battery after an alleged altercation with her husband Ryan Dorsey in Kanawha County, West Virginia.

She and Dorsey are parents to 2-year-old son Josey Hollis.

For six seasons, from 2009 to 2015, Morrison and Rivera starred in the Ryan Murphy-created musical comedy-drama television series. Morrison portrayed glee club director Will Schuster and Rivera stole laughs as McKinley High School student and cheerleader Santana Lopez.

Though he has not kept in contact with Rivera these days, Morrison has stayed close to another familiar face from Glee: Gwyneth Paltrow.

“We became really good friends on Glee and she’s someone who’s been a constant supporter in my life,” Morrison told PEOPLE on Sunday about Paltrow, who guest starred in five episodes as substitute teacher Holly Holliday between 2010 and 2011.

Paltrow is reportedly engaged to boyfriend of two years Brad Falchuk, who co-created Glee. The couple first met when she joined the show in 2010 for a season two guest spot.
