J. T. Hellstrom and Colleen Carlton are fictional characters and a supercouple from the American CBS soap opera The Young and the Restless. J. T. was portrayed by Thad Luckinbill, and Colleen was portrayed by three different actresses during the pair's time together, including Lyndsy Fonseca, Adrianne León, and Tammin Sursok. They are often referred to by the portmanteau "Jolleen" by fans on internet message boards and in magazines. Many other famous celebrities appear on this show.

Beginning as a controversial pairing due to the characters' age gap, their pairing would soon gain popularity, characterized as "Genoa City's sweetest supercouple". Former head writer and executive producer John F. Smith pushed for a story between the characters despite the unexpectedness and controversy surrounding them. Luckinbill's musical ability was an element in their storyline as the actor wrote and performed two original songs for the soap opera. The song "When You Say Nothing at All", performed by Alison Krauss, was also used during their storyline.

Development

Relationship

The original storyline designed for J. T. and Colleen centered around an unrequited crush she feels for him. Luckinbill and Fonseca, the first actress to portray Colleen, thought their character's relationship would progress no further than friendship. Fonseca said that if they became a couple, the fun brought on by the "tug-and-pull" element between them could disappear. Luckinbill considered the age difference too great an obstacle to overcome, as at the time, J. T. was 18 years old and Colleen was 15. Smith later pushed for the plot to be taken further and the characters were paired romantically. Both soap opera critics and members of the show's cast and crew considered this a controversial and surprising move. Fonseca stated she "wasn't expecting it at all", and admitted that even former executive producer David Shaughnessy found the pairing "shocking".

J. T. and Colleen

The writers used J. T.'s relationship with Colleen to bring out a more sympathetic side to him that the audience up to that point never witnessed before. Smith characterized their storyline as "taking this guy on the journey from wild college kid to being in love with this little high school sophomore". They also positioned Colleen as the aggressor in the relationship by scripting her as pursuing J. T., while he, in an uncharacteristic move, held off because of the difference in their ages. The writers "carefully navigated the development of this relationship, emphasizing its tender, supportive aspects." They scripted them as "ferociously protective" of each other.

J. T. and Colleen

Other obstacles written for the pair included the opposition of Colleen's family to the pairing, J. T.'s music career, and third party characters who came between them. In 2003, J.T. cheated on Colleen with Anita Hodges, an older woman considered a "sexy cougar". Luckinbill explained J.T. as being "weak in a desperate moment", and that he "felt really sorry for someone he's known his whole life, and the good side of J.T. emerged to offer Anita some comfort. Then it got really out of hand." He added that J.T. "cares deeply" for Colleen and "realizes she will be devastated by his actions". Luckinbill felt that J.T. "wouldn't hurt her for the world, and yet that is exactly what he'll end up doing". In May 2004, Fonseca's contract was not renewed and she was confirmed to exit. Within the storyline, Colleen leaves Genoa City and J.T. because she does not want to stand in the way of his music career. However, she returned to reprise the role briefly that December. J.T. had begun dating Brittany Hodges (Lauren Woodland) and the writers wanted to bring Colleen back to "add more complications to the story". Luckinbill described his character's feelings for Colleen and Brittany as extremely different, saying: "J.T. saw Colleen as somebody so opposite himself that he considered himself undeserving of her love. She was too angelic [whereas] Brittany has more of the 'black sheep' in her." Fans of the pair campaigned for a reunion between J.T. and Colleen when Fonseca returned, and pushed for her to be put back on contract. Fonseca and Luckinbill also anticipated the repairing of their characters because of a positive viewer response. Fonseca described it as being "the best part of coming back", stating: "Already it seems the fans [are] excited to see us together again." Luckinbill stated: "When they were together, they were like some sort of supercouple and there is a huge amount of fans who still want them together." News of Fonseca's second exit incited a fan outcry and a campaign pushing for the actress's permanent return. Fonseca made her final appearance as Colleen in February 2005.
