Those close to the 28-year-old singer are concerned about his crumbling relationship with Jessica, and are putting pressure on him to work through their problems.
A source said: Justin's friends are usually all about anything he wants, but in this case, his boys are totally disappointed in him. They think he's making a big mistake. Justin and Jessica have their problems, but all in all, his friends think she is one of the best things that ever happened to him.
Justin had been relying on his pals to go to nightclubs with him when his relationship hit the rocks, but they have not been keen on the idea.
The source added to FOX 411 blog: They really thought he got past all of that. But it's all beginning all over again. They think if they don't give in he may come to his senses and sort out his relationship. That's what they really want to see happen.
Earlier this month it was claimed Justin was re-evaluating his two-and-a-half year romance.
Neither Justin nor 27-year-old Jessica have commented on the break-up claims.
