TLC made the announcement by posting a Facebook video on Monday showing the three confirmed couples for Season 4.

"COMING SOON #90DayFiance: Happily Ever After. Which couples are you excited to catch up with?" wrote the show's official Facebook page alongside the video.

Colt and Larissa's 90 Day Fiance: Happily Ever After? participation had been widely expected as Larissa had already repeatedly revealed it in her social media postings.

"I already finish in early December happily ever after," Larissa told her Instagram followers during a Q&A session with fans in February.

Colt's cousin John Maymoun had also told RadarOnline in December that Larissa and Colt -- who are now in the process of divorcing -- were in the process of filming Season 4 of 90 Day Fiance: Happily Ever After?.

The two couples join Chantel Everett and Pedro Jimeno, whom the network had already revealed as 90 Day Fiance: Happily Ever After? Season 4 cast members.

Chantel and Pedro's Happily Ever After? Season 4 participation was announced in a promo that aired during 90 Day Fiance's Season 6 Tell-All reunion special in January.

While the network hasn't announced an exact premiere date yet, 90 Day Fiance: Happily Ever After?'s fourth season is scheduled to debut this spring.

The Happily Ever After? season will reportedly star a total of six couples from the 90 Day Fiance franchise, leaving three additional couples still unannounced by TLC.

However, according to RadarOnline, prior Happily Ever After? couple Nicole Nafziger and Azan Tefou will be one of the three unannounced couples that will be part of 90 Day Fiance: Happily Ever After?'s fourth season.

Nicole and Azan, who most recently appeared on Season 3 of 90 Day Fiance: Happily Ever After?, reportedly began filming footage for the new season in November 2018.

90 Day Fiance Season 6 couple Ashley Martson and Jay Smith also filmed footage for 90 Day Fiance: Happily Ever After?'s fourth season, according to Ashley.

However, in February, Ashley announced she and Jay had decided to "quit the show" and publicly accused TLC and 90 Day Fiance producers of being the reason why she and Jay had scammed their fans by faking marriage problems and pretending they had separated in December and their marriage was on the rocks.

Ashley -- who filed for divorce in early January, but then withdrew the filing only days later -- also claimed she and Jay never separated and TLC "ruined" the credibility of her marriage.

"The final straw was when our story started to become inconsistent because of what we were being asked to hide and not tell followers... We want our old life back. We're over being celebrities," Ashley told RadarOnline last month.

TLC has not commented on Ashley's allegations, or stated whether or not she and Jay will be part of 90 Day Fiance: Happily Ever After?'s Season 4 cast.

Russ and Paola, who are married with one child, starred on Season 1 of 90 Day Fiance and later appeared on Seasons 2 and 3 of 90 Day Fiance: Happily Ever After?.

Russ was 27 and from Owasso, OK, when he met Paola, a 26-year-old from Bucaramanga, Colombia, while he was on a work assignment in the petroleum industry.

The pair got married and moved to Tulsa. Russ and Pao, however, later relocated to Miami, FL, so that Pao could pursue modeling and personal training.

Russ and his wife are still together, with Russ calling Pao "my first, my last, my everything."

Paola gave birth to a baby boy on New Year's Day 2019, just after midnight. She and Russ named their son Axel.

As for Colt and Larissa, their storyline on the spinoff is expected to be a trainwreck that will be uncomfortable to watch.

Colt, a 33-year-old software engineer from Las Vegas, NV, and Larissa, a 31-year-old from Brazil, met face to face for the first time in Cancun, Mexico, after starting a relationship online.

It only took five days for Colt to realize he wanted to spend the rest of his life with Larissa, and so he proposed marriage to her, and then Larissa moved into Colt's shared Las Vegas home with his mother.

Colt and Larissa eventually got married and tied the knot on June 24, 2018, according to Clark County Clerk records obtained by Reality TV World.

However, Colt and Larissa's relationship remained extremely volatile in the months following their wedding, and Larissa was arrested multiple times for domestic violence.

Larissa also accused Colt of cheating on her and flirting with other women.

"Colt is cheating [on] me with this girl!" Larissa captioned a December Instagram posting of screenshot of a text-message exchange between Colt and the woman. "And [he has] plans to use me until he finish Happily Ever After."

However, on January 10, Colt and Larissa got into a violent late-night fight that left both parties bloodied and resulted in Larissa later being arrested for domestic violence for a third time.

Colt filed for divorce in Clark County Court the following day, according to court records obtained by Reality TV World, and the couple is currently in the process of divorcing.
