Rihanna is set to bring her "Last Girl On Earth" tour to Australia next year & to promote the outing, she is starring in a new commercial--alongside penguins!--for the Australian phone service Optus through which fans can purchase tickets to her show. Come to think of it, this commercial doesn't make an ounce of sense! But, it's cool. Hehe. RiRi's latest album Rated R is out now.
