The estranged husband of the Britney Spears was reportedly unimpressed when he heard Howie Day had spent the night at Britney's house.
A source told America's Star magazine: "When Kevin heard they had a sleepover at her house, everyone wanted to know about it.
"He lit up a cigarette and said he guessed you have to head to the dump to find trash, referring to how Britney and Howie met while in rehab."
Britney met musician Howie while she was allegedly treated for alcoholism and post-partum depression at Malibu's Promises Centre.
Bad boy Howie was arrested in 2004 for allegedly locking a fan in the bathroom of his tour bus when she rejected his sexual advances.
