Riley Keough stars in sexy Bonds lingerie ads

Riley Keough, Elvis's eldest granddaughter, has signed on to be the new brand ambassador for Australian lingerie line Bonds.

The 24-year-old model-actress made her debut for the brand in its new "Lacies collection" ads which feature her, as a redhead, in hip-hugger panties and boy shorts.

In recent months, the "Runways" star has been linked to Twilight star Robert Pattinson, who recently broke up with longtime girlfriend Kristen Stewart. However, a representative for Keough told Just Jared that the rumors were fake.
