His mojo meltdown freezing her heart

DOWN-IN-THE-DUMPS hitmaker Justin Timberlake's poor-me 'tude is bumming out wife Jessica Biel, who is desperate for him to bring sexy back, sources dish to GLOBE!

Not only is the Cry Me a River singer, 44, constantly moaning and groaning about his disastrous Forget Tomorrow world tour and other woes, he's also looking like a washed-up old man with his unkempt gray beard.

And it's all a big downer for the Candy star, 43, who finds every Zoom call with him a major downer. “He’s just miserable on this tour. Every time they check in, he’s downbeat,” an insider says.
