Kylie Jenner and rap star boyfriend Tyga are rumored to be attending therapy sessions in a last ditch effort to save their suddenly fragile union.

"It's been hell," a source told Radar Online of the couple's less than year-old relationship, which almost from the very start has been dogged by rumors of infidelity and ongoing drama with Blac Chyna, the mother of Tyga's young son.

"Kylie's not coping at all and Tyga is just as unhappy," the source added.

In the face of all that tension, reports are it was Khloé Kardashian who suggested the therapy sessions because "they've had to cope with a lot and could do with some emotional guidance."

As for the couple's once much discussed plans to get married or even elope, a source added Jenner and Tyga still plan to walk down the aisle. However, the two now want to be 100 percent sure and "trusting of each other" before doing so.

Several media outlets have recently reported the 18-year-old Jenner and her paramour, seven years her elder, have been bickering nonstop, making her wonder if her rapper beau might be too young and immature for her.

"It is to the point where it is almost annoying to be around them because they create such an awkward situation," a source said.

Among all the recent rumors that have impacted the couple are allegations of Tyga's dalliances with a transgender woman known as Mia Isabella, and reports Kylie cheated soon after her 18th birthday with a Miami rapper named Stiches.

"I had sex with her," said Stitches, born Phillip Katsabanis.

"We did it all," he added, alleging that the two also did cocaine during their time together.
