New Kids on the Block have been criticised for asking journalists reviewing about a recent concert in Washington to mention the show's sponsor.
The sponsor? Toilet paper brand Cottonelle.
The free show was promoted by asking fans to attend "commando" - that's without underwear - and an accompanying video interview with the '90s boy band suggested they would be performing commando too.
In the video, the band says going commando is "very rock and roll". One of the band's singer's is draped in the sponsor's product.
