Just a week after saying ‘I do’, Riley Keough looked to be in the throes of wedded bliss as she relaxed with new husband Ben Smith-Petersen on honeymoon.

The 25-year-old granddaughter of Elvis Presley beamed for the camera as she sat cross legged on a beach in Hawaii on Saturday.

The beauty, who looks remarkably like her mother Lisa Marie Presley, showed off her envious bikini body in a mismatched two piece as she relaxed near the water’s edge.
