Wacky rocker Lady Gaga has a very saseh proposal for the Jonas Brothers.

The super-sexed fashion wreck disavows Disney's fave purity ring enhanced tween idols vow of chastity - she wants to bed 'em.

Gaga, 23, admitted she'd "like to have a foursome with them."

"I love them. They're very talented!"

But the self professed virgins may not be so - in bed.

And besides what would Uncle Walt - much less Mama Jonas think?!!
