Justin Timberlake battled "wedgies" while wearing skimpy swimwear for his new movie.
The musician-and-actor, who stars alongside Mike Myers in 'The Love Guru', felt confident in the tight trunks but found it tough when they became wedged between his buttocks.
He told US TV show 'Extra': "This may be TMI (too much information) but I was constantly digging out those wedgies. "I work out pretty diligently. At the time I was on tour, I worked on this film for 10 days. I was on tour so I was in shape."
Meanwhile, Mike - who also co-wrote the film - insists Justin didn't need much persuading to strip off and bare his body. He said: "He's not an uncomfortable person. The trunks are getting some very good reactions from people. Some people are very happy about them!"
'The Love Guru', which also stars new mother Jessica Alba, will be released in cinemas this summer.
