Last April Gavin Rossdale and Gwen Stefani officially ended their marriage - and since then Gavin's been looking WORSE THE WEAR.
It's not clear whether he's gone into some sort of depression or what . . . but dude was looking MISERABLE in Vegas last weekend.
It could be because the split couple have put their $35 million Beverly Hills home they used to live in together on the market (and maybe it's not getting any biters).
It could be because Gwen and Blake Shelton are happier than ever.
Could be that that nanny was a REALLY BAD MISTAKE.
