In an exclusive sneak peek at Sunday's episode of TLC's I Love a Mama's Boy — which shows women navigating their partners' inappropriately close relationships with their mothers — groom-to-be Ethan partners with mom Esther to rehearse their mother-son dance for Ethan's upcoming wedding to fiancée Leyna. "I love Ethan so much," Esther says. "He's my little Cookie Monster, and the wedding means everything to me." As the duo discuss the routine with dance instructor Jose, Ethan specifies, "We want it to be romantic, sexual, sensual, everything." In a confessional, Jose laughs nervously and reveals his gut reaction: "I was like, 'What?' I think he was joking, but I think he might not have been joking too, so who knows?"

"This is something that every mother of a son dreams about from the day their baby's born." She continues, "Ethan wants to dance to 'Sexual Healing.' I said, 'Make it memorable!'" At that point, bride-to-be Leyna enters the studio with an awkward, "Oh my!" It doesn't take long for her to cover her eyes and turn her head away from second-hand embarrassment. "When I first met Ethan, I did know that he was really close with his mom," Leyna shares in a confessional. "I found that out pretty quickly." TLC Back in rehearsal, Ethan says, "I like the thing when she just walks on me. I feel like a baller. I got this hot MILF on my back." Admits Leyna, "The flirting really does bother me, and I do think it's weird that I do get jealous of Esther and Ethan's relationship just because I don't think anyone has every really had to feel that way about their significant other and their mom." She continues, "It's hard to ignore because it looks like they're more together than we are — but it's something I've gotten used to."

Leyna says in a confessional: "Sometimes I get a little jealous because, like, Esther will come out in a bathing suit, and [Ethan] will be like, 'Oh, you look so sexy!' And I'm like, 'I didn't get a 'sexy' or anything like that.'" But Ethan says Leyna "understands" his dynamic with his mother and "knows that it's all fun and games."

Esther replies, "Oh, he's my baby." Later, she adds in a confessional: "Leyna gets jealous, but that doesn't mean [Ethan] has to stop giving me that affection and attention."
