Joey Lawrence is accused of having an affair with his married co-star Melina Alves during his separation from Samantha Cope

Wow.

Joey Lawrence is accused of having an affair with his co-star – and the actress' estranged husband is the one making the explosive allegation in his new divorce filing.

Edward Rider claimed in documents filed in New Jersey and obtained by TMZ on Thursday that he discovered in late March that the 48-year-old “Blossom” alumnus was having a sexual relationship with his then-wife Melina Alves.

According to IMDB, Lawrence and Alves co-star in the upcoming film “Socked in for Christmas,” which is currently in post-production.

Rider reportedly claimed his wife cheated on him with the former Brotherly Love star while they were together in California. It's unclear if the Christmas movie was filmed there.

However, another cast member posted on Instagram in June that he was in Hollywood for a promotional photo shoot for “Socked in for Christmas,” so that was likely the filming location.

Rider reportedly believes that Lawrence and Alves' alleged affair lasted for some time.

TMZ reported that the allegedly jilted ex mentioned in the documents that he thought the actors met at “different” times and places.

Page Six reached out to representatives for Lawrence and Alves but did not receive an immediate response.

The cheating scandal came a day after the “Melissa & Joey” alumnus’ estranged wife, Samantha Cope, filed for divorce after two years of marriage.

In court documents obtained by Page Six, the 37-year-old “Frankie Meets Jack” actress cited irreconcilable differences as the reason for their separation and requested sole custody of their one-year-old daughter Dylan Rose.

Cope also waived her right to spousal support, pointing out that she and Lawrence had been living apart since June, two months before the divorce was filed.

According to TMZ, Rider filed for divorce in July, just weeks after Cope and Lawrence split and shortly before the “A Deadly Deed” star filed her legal papers.

Page Six reached out to Cope for comment on the fraud allegations but did not receive a response.

In June, she shared a cryptic message expressing her optimism about the big changes to come in her life.

“Not everything you lose is a loss. Some things mean freedom,” read a quote on Cope's Instagram.

“Some things are a second chance. Some things are a miracle in secret. Some things mean a long overdue distance, clarity for blurry eyes… Some things are healing.”

Lawrence was previously married twice, to Michelle Vella from 2002 to 2005 and to Chandie Yawn-Nelson from 2005 to 2022. With the latter he has two daughters, Charleston, 18, and Liberty, 14.

Lawrence and Cope met on the set of the Lifetime series “My Husband's Secret Brother” and were engaged in August 2021, before his divorce from Yawn-Nelson was final.
