Jake Gyllenhaal Cops a Peek at Half-Naked Sis

Well, those Jake Gyllenhaal gay rumors can finally be brushed under the rug.

Unfortunately, there’s another aspect of his sexuality to ponder.

Maggie Gyllenhaal tells Us Magazine that her little bro gave her a ribbing over her sexy Agent Provocateur lingerie ads.

“My brother [Jake] called me and said, ‘I’m in Heathrow [airport in London], and there’s a 12-foot picture of you upside down in a negligee!’ “

Ha-ha, that’s pretty funny!

Suddenly, Angelina Jolie and her brother’s spit-swapping Oscars performance seems downright wholesome. At least by showbiz-family standards.
