SWEET TREAT

The Dark Knight star Maggie Gyllenhaal satisfies her sweet tooth with a taste of the new Ben & Jerry's ice cream "Imagine Whirled Peace" Tuesday, during a "Peace Bed-In" at the Ben & Jerry's Times Square Scoop Shop in New York City. The John Lennon tribute flavor is caramel and sweet cream ice cream with toffee cookies and chocolate peace signs.
