The mother-of-two wore a collared shirt, black jeans and glasses for her appearance.
JWoww, 33, filed for divorce from Roger, 44, in September 2018 after three years of marriage and two kids.
The reality star filed for a restraining order against Roger in December 2018 after an alleged domestic violence incident at their New Jersey home.
JWoww and Roger's relationship has improved in recent months. They are focused on amicably co-parenting their children, and JWoww even invited Roger to their daughter Meilani's 5th birthday on July 13.
However, there's zero chance of a reconciliation, as JWoww has moved on with new boyfriend Zack Clayton Carpinello, 24.
The brunette beauty and her new beau made their red carpet debut as a couple at the CMT awards on June 5.
JWoww listed her marital home for sale in June 2019 for $1.45 million.
