Nick Lachey has been branded a "d**khead" by 5ive member Scott Robinson.
The 34-year-old singer has hit back at the former 98 Degrees star, who recently labelled the 'Everybody Get Up' hitmakers "the worst boy band of all time" after the two groups butted heads while touring together in the 1990s.
Scott exclusively told BANG Showbiz: "If you want to quote me, the guy's a d**khead!
"The only reason Nick's saying anything is because he's desperate for a bit of press because he's not doing anything at the moment."
Scott's bandmate Sean Conlon appeared to be oblivious to Nick's damning comments in an interview with US talk show 'Watch What Happens Live' earlier this week, and Scott was only too happy to fill him in.
Scott told his pal: "Nick from 98 Degrees - you won't remember them because they were s***e - but Nick was slagging us off to the press saying we were lame. He's the one with the 98 Degrees tattoo!"
The singer added: "If I'm going to be completely honest, the only reason he's saying that is because we were on the Smash Hits tour with him. There were three bands - he was one of them - and 5ive won the tour, so we won the award, so he's upset. He had bigger muscles than me but he didn't have the award."
The 5ive stars also quipped that Nick, 40, is desperate to join 'The Big Reunion' in a bid to boost his career.
Scott teased: "He probably wants to get on 'The Big Reunion' ... he wasn't asked and he's really p***ed off about it. He was on a small telly programme in America and he thought, 'Oh, I know, I'll mention a bigger band than I'm in and get some press.' "
5ive are set to join fellow 'Big Reunion' groups Blue, A1, 911, 5th Story and Damage on The Big Reunion - The Boy Band Tour in October. Tickets go on sale on Saturday March 22.
