"I have five beautiful children by four different women," Robert said in a 90 Day Fiance teaser clip for the show's November 24 episode that aired during TLC's 90 Day Fiance: Pillow Talk broadcast on Sunday night.
Only Robert's son Bryson, who lives with Robert, has been featured or even mentioned on the three 90 Day FianceSeason 7 episodes that have aired on TLC so far.
Robert's new fiancee, Anny, a 30-year-old from Santiago, Dominican Republic, apparently also wasn't aware of Robert's additional children and baby mamas prior to the disclosure that will air on next week's 90 Day Fiance broadcast.
"What the f-ck?!" she tells cameras in the promo after learning her fiance has gotten four women pregnant and is the father of five kids.
At the time, Robert was anticipating Anny's arrival into the United States following her flight from the Dominican Republic.
Anny traveled on a K-1 visa, and so Robert was hoping to get to know her better and get married within 90 days. (Robert had only spent one day with Anny in person when he popped the question).
Robert hoped Anny would help him take care of Bryson since he worked and she wouldn't be able to work upon her entry into America.
"My biggest fear when Anny gets here is that she's all about money and doesn't care about me and Bryson," Robert said in premiere.
Sunday night's TLC broadcast of 90 Day Fiance's third Season 7 episode had showed Anny expressing frustration about Robert's financial situation.
After spending their first night together following Anny's arrival in America, Anny asked Robert to take her shopping for new clothing the next day. Anny apparently didn't bring much to the United States with her and had instructed her sister to sell the clothing she had left back home.
Anny's shopping experience with Robert, however, did not meet her expectations as, unbeknownst to Anny, he took her to a second-hand clothing store. She complained there were "a lot of ugly rags" in the store and she had envisioned Robert buying her fashionable clothes famous in America, such as designer brands Chanel and Versace.
"That's f-cked up," Anny said about the clothing in the used clothing store Robert had brought her to. "Rubbish."
Robert asked Anny to keep an open mind about the clothing as she called each and every piece "ugly," but she simply hated everything in the store.
Anny then learned all the store was a second-hand shop and much of the clothing had been worn and used before. Anny said she was used to buying new, nice and sexy clothes in the Dominican Republic, and wasn't happy.
Robert told the cameras Anny was "very selfish" because money doesn't grow on trees. He wasn't happy with her and couldn't believe how she had acted in the store.
"I never buy used clothes in my country. All the clothes I buy are expensive. I am poor but I don't use f-cked up clothes," Anny told Robert.
Robert was upset with Anny for acting like she was "all that" at the thrift store, but he decided to put the argument behind them and enjoy a nice dinner out. Anny felt frustrated because Robert had allegedly promised her a lot and she was used to looking nice in the Dominican Republic.
She didn't appreciate how Robert's surprise was taking her to a thrift store instead of a mall.
When the pair went out to dinner later, Anny said she'd love to have a similar seafood menu at their wedding, but Robert said there was no way he'd be able to afford that -- and he wasn't okay with the idea of people eating and drinking off his budget.
Anny was surprised to hear Robert wouldn't want a big wedding.
The couple's tension then escalated further when Anny said she'd like to have a ceremony and reception in Miami Beach, to which Robert replied, "Do you think I'm made of money?! Courthouse and boom. That's it."
Anny didn't want to get married at a courthouse, and she said Robert had promised her they'd have the wedding of her dreams. Anny also implied Robert was not living up to her expectations, and she said she'd like to move to Miami, FL.
Robert became angry and told Anny to move to Miami by herself.
"I don't want to hear about Miami. Just appreciate where we live," Robert vented to the cameras.
Anny then asked Robert to apologize for his behavior -- which included swearing -- and he said, "I'm sorry you are inconsiderate and a big-ass crybaby. How about that?"
Anny said Robert had promised her a lot and he wasn't doing any of it, but Robert argued he wasn't the problem.
Robert called his first full day with Anny "a disaster" and said she was "ungrateful and selfish" and everything he did for her didn't seem to be enough.
Anny told Robert not to marry her if he was so unhappy with her, and she reminded Robert he had promised her an iPhone10 and expensive clothing.
Anny called Robert "a liar" and noted he had done nothing for her. The pair also later bickered about which person was going to sleep on the couch at his apartment that night.
However, the couple was tired of arguing, and so they both decided to stop fighting and enjoy their night together since Bryson had a babysitter. Robert then surprised Anny with a gift, and it turned out to be sexy lingerie. The couple therefore kissed and made up.
While 90 Day Fiance has not shown any indication Robert has additional children before Sunday night's promo aired, his Instagram bio did indicate he has more than one child.
"Loving dad love my children born in the number one city in the world NYC," the Brooklyn native's bio states.
